Same here with Files on Sharepoint and Teams. Local Files or Fileservers no problem.
If local Powerpoint Files are open, too, all Powerpoint-Processes are ended.
The online ones are not that big problem, because autosave is on, but the onprem ones are annoying because work is gone till last save-action.
We can't find any correlation. Sometimes it happens 20 times in 5minutes and sometimes 2 times a day.
