How to fix performance problem with Microsoft Word, extremely slow and lagging doing basic tasks, typing etc.

I am experiencing ongoing performance problems with Microsoft Word. The program is extremely slow and lags during basic tasks such as typing, opening documents, copying, pasting, and editing. I have already completed all recommended troubleshooting steps, including uninstalling and reinstalling Office, checking for problematic add‑ins, and attempting to disable hardware graphics acceleration (which was not available as an option). I also opened Word in Safe Mode, but the issue continued. No corrupt system files were found, and the problem has persisted for a long time despite having a paid subscription to Microsoft Office. My is how do I correct this long-standing issue and what else could be causing Microsoft Word to run very slowly and lag during typing, editing, and opening documents, even after reinstalling Office, checking add‑ins, attempting Safe Mode, and confirming that no system files are corrupted?
