Is this a new problem or was the Mac working properly at first?

What system changes and/app installations did you make just prior to the problem's start? Some 3rd party apps just don't play well; try uninstalling WinDeskTop and restarting to see if that's the problem. Monterey is not fully supported by all apps that will install.

Do you have installed any AV, fixer, cleaner or optimizer apps? If so uninstall the all using the developer's instructions, restart and retest.

Ensure that you have the current version (e.g. April 2022, 22.001.20112) of Acrobat DC Pro¹ and not some older version that may not be compatible with Monterey. Check that Qsync is supported on Monterey and you have its current version.

¹ Windows version is Apr 2022, 22.001.20117.
