Dell Latitude 5550 Consistently Freezing When Microsoft 365 Apps Are Opened.

**Edit: FIXED!** **I ran the following commands in admin terminal, and scannow found and repaired corrupted files:** **DISM /Online /Cleanup-Image /CheckHealth** **DISM /Online /Cleanup-Image /ScanHealth** **DISM /Online /Cleanup-Image /RestoreHealth** **sfc /scannow**

**I also uninstalled and re-downloaded 365 in 32bit instead of 64bit.**

I need help!

Everything seems to be completely fine with the computer until I try to open Excel, Word, Powerpoint etc. Seemingly only Microsoft 365 apps are causing the issue. This issue started happening out of the blue yesterday morning. When I open either an Excel file or the Excel app, the computer doesn't seem to do anything for a minute or two and then freezes everything. It temporarily unfreezes after a few minutes, but is only unfrozen for a few seconds before locking up again. If I try to open the program a second time during the first delay when nothing seems to happen, it immediately freezes everything.

I am running a Dell Latitude 5550 with Windows 11 Pro 23H2 Intel(R) Core(TM) Ultra 5 125U 1.30 GHz 16.0 GB (15.5 GB usable)v

I have uninstalled and reinstalled Microsoft 365. I have updated drivers. I have uninstalled and reinstalled Dropbox. I have ended task, "explorer.exe" and restarted it. I have run basic malware and virus detections - no threats found.

I'm kind of at a loss of what to do/try next.

Please help!
