Hi Pavlo,
Thanks for posting in the community. We are happy to help you.
According to your description, the Office applications will utilize a lot of memory and may cause them to freeze. I have tested it on my side, but I can't reproduce the same situation. So, to troubleshoot and narrow down the situation, I recommend you try the following suggestions, then check again.
- Please try to move the related cache folder to Desktop, then check again
a. Close and quit Word and PowerPoint
b. Use Finder, press Shift + Command + G, copy and paste the path ~/Library/Containers/, find and move the folder Microsoft Word and the folder Microsoft PowerPoint to Desktop, then run Word/PowerPoint and check again.
- If the situation still happens, please switch to another Mac user profile (if you don’t have another Mac user profile, please create a new Mac user profile, then switch to the new user profile), run Word/PowerPoint, and check again.
We look forward to your response. Thanks for your cooperation.
Sincerely,
