I get this non-stop, to the point of making VS nearly unusable. I am on the latest builds of both the pre-release (17.12.0 Preview 2.1) and the release branch (17.11.4), and if anything it has gotten worse as I've upgraded.

To resolve the issue I set "Run background code analysis for" to "None".

It’s not the real solution, because it doesn’t analyze more in background, but at least it didn’t give me more problems.

Same problem here, running VS 2022 v17.13.6 on a Dell Inspiron laptop with a Core 7 150U processor and 32GB memory - all Dell and Win 11 updates applied. We have tried:

Repairing VS

Uninstalling / reinstalling VS

Cleaning the cache

Setting 'run background code analysis for' to 'none'

Despite this, the issue is happening several times a day, but only for one of our devs. Is a laptop of this spec just not up to running VS?

I'm also having this issue.

I reached out on X ... no response from anyone there yet ...
https://x.com/CoderPW/status/1925935258324652049

It seems to be an issue in larger codebases.
It's like it's not managing the workload properly and tasks are just timing out in a queue as a result.

I believe this to be the root cause of BSOD's in my case.

No one has mentioned Burst, but I found that was the cause of my issue.

Now I have a niche setup, because I'm opening decompiled C# code for a video game, but all I had to do to get Visual Studio to stop hanging after a minute was delete the Burst Attributes from the Properties/AssemblyInfo.cs. I'm certainly not re-compiling this code so it's no problem for me but that was the root cause, as the previous game version worked fine which didn't use Burst.

Hello @Starfall Conquer ,

Welcome to Microsoft Q&A forum.

I suggest first try cleaning VS cache(rename ComponentModelCache folder(s) in C:\Users\username\AppData\Local\Microsoft\VisualStudio\17.0_xxxxxxxx folder), and then reset VS(run devenv /ResetSettings command in Developer Command Prompt For Visual Studio 2022) => run Visual Studio as administrator.

Sometimes, updating Windows OS or uninstalling Newtonsoft.Json assembly file(run gacutil -u Newtonsoft.Json in command prompt) works.

Please feel free to let us know the results.

Sincerely,

Tianyu

Hi @Starfall Conquer ,

Thanks for your reply.

Did you use any extension or any third-party programs along with VS 2022? When did this error appear? Does this error appear in a specific situation or after some specific actions?

Hi @Starfall Conquer ,

Thanks for sharing more details.

It’s random, I am considering if this is a potential/known issue. I know, there’s a similar/same(not 100% sure) issue => "SyntaxTree is not part of the compilation" reported when applying SuppressMessage to generator diagnostics which has been fixed but still > Pending Release(fixed in VS 2022 version 17.7 Preview 2). Please kindly check it. If you got the same issue, I’m sorry, you may need to wait for the newer release version of VS.

BTW, here’s another similar ticket: RemoteSemanticClassificationService.GetClassificationsAsync: SyntaxTree is not part of the compilation which is Under Investigation. If the error is different from yours, could you please submit a ticket on our Developer Community for further check?

This is still a major issue. I've followed multiple steps stated above and I'm still encountering this. It gets even more annoying where if you ignore it. Sometimes your visual studio just crashes out. Forget saving anything because you don't have time.

Event logs show the following image. I've uninstalled all .NET Frameworks and reinstalled, I even clean installed Windows 11 Pro and did fresh everything. Still seeing this issue. 👁 User's image

Here's a view of what it looks like in my Visual Studio Enterprise 2022 (64-bit) 17.8.3

Now I added the full photo, so you can see the scroll bar just goes on for days with errors. I'm also curious why Visual Studio is built with .NET Framework 4.8 when we're on .NET 8 now. This could very well be the issue since every month it seems Microsoft is pushing security patches for 4.8.

Please fix this, it's become exhausting and I really don't feel like switching to Rider.

Hello @FallenDev-1649,

Thank you for taking time to post this issue in Microsoft Q&A forum.

The error code -1073741819 seems to be related to access. Are you using any antivirus software, proxy, extension, or is there any permission limitation on your machine? Is this issue project-specific?

I have the same exact issue. I noticed since 12/30/2023 I had an issue building my projects because of a false positive of Microsoft Antivirus. I added an exection for msbuild.exe, devenv.exe and my project folders. And the anitvirus error was gone. However since a few days I encountered this error code -1073741819 @FallenDev is describing.

@Tianyu Sun-MSFT Thank you for the reply, aye I also saw that. I actually tracked down this issue this morning as a faulty RAM stick. Currently running through the RMA process with GSkill. Seems I started having memory failure a few weeks ago and its causing access issues.

Sorry for the miss association above, it mirrored itself as the problem mentioned prior, but seems mine is hardware related.

Hi @Sebastian S,

You may double check your system environment, probably some issues hide in your system environment and cause the access issues.

Hardware issue is one of the situations, some third-party extensions, programs may also cause this issue.

Do you have full permissions on your machine? Did you install some "special programs" which may block the access?

Hi! I'm not sure in what scenario you're getting this error. In my case it was while trying to train model for text classification. When using vs22 the error occurred, but using mlnet cli tool allow me to train model succesfully. So it was solution for me.
