So there are not steps you suggest other than contacting QB, have them remotely log in and fiddle around to fix. As a small business owner I don't have the extra time required to just hang on the phone for what will probably be a an hour +.

Nothing was updated when my QB stopped loading in Parallels, I had checked or I would have rolled back the update. 

I have ran the QB Tool Hub - almost every thing to run there. 2023 runs fine, 2024 nope, not a chance. So I have to resort to an older machine, thankfully that does have Windows 11, to process/run payroll & payroll tax. 

There has to be suggestions offered.
