I have been having the same trouble.  Sometimes when opening quickbooks desktop 2022, but mostly when changing companie files, chrome, file explorer or outlook (365) would close.  Didn't happen every single time I switched company files, but I work in several company files a day, so it happens a couple or more times a day.

It didn't make a difference if I was in multi-user or hog mode.

Today I made sure everything was updated: QB's, windows 10, office 365.

Then I disabled the QBWC in services.  

I turned off Intuit Data Protection in startup.

then I rebooted my computer.

I have switched company files several times now, and can't seem to get it to crash anything now.

Also, switching company files now seems to load MUCH faster.  

I don't think I need Web Connector anyways, as I don't sync or download any financial accounts.

I'm hoping this fixes it.
