High CPU for multiple processes Microsoft 365

In the last several days I have noticed my laptop CPU fan blowing constantly. The culprit seems to be 4 identical processes using the same amount of CPU as each other continuously hovering at about 8-12%. This keeps the fan blowing 24/7.

The Task Manager shows the Process name as "Microsoft 365 and Office (32 bit)" and no Office applications are running. When I view the details the executable names are "odt____.tmp.exe" with the underscores representing some 3- 4-character hex value, e.g. C67A.

I can end the tasks but they come back after a time and the CPU fan turns on again.

What are these processes and can I turn them off?

TIA

BTW, I tried to include a screenshot, but the image upload doesn't work.

    Seeing this on an intune joined device here. Even after updating to the latest version of Office, a few of these files are still present in task manager.

    Would love to know a solution!

    This issue was happening on multiple machines, and I noticed that it was not occurring on my machine, I observed that on the affected machines the office applications were up to date on the latest release. I then proceeded to update office apps on my machine to the latest release and the issue then started to occur on my machine. I am guessing something about the latest office release is causing the issue.

    I followed these steps on my machine to roll back to a previous version and it appeared to resolve the problem.

    Running Task Manager as an admin seems to show more process detail, ie: process is Microsoft 365 and Office (32 bit). I've seen 4-8 of these running so far.

    interesting on the disabling Windows Hello for Business. We recently had it enabled and switched back to non-configured. I'm not sure the two are related, as the process in question if Microsoft 365 and Office (32-bit). I've seen up to 8 of these processes running on a machine taking up the majority of the CPU and brining machine to a crawl. Killed processes on two machines and updated Office to current. I haven't seen the processes return yet, but we have restarted the machines either.
