Downgrade away from Sonoma back to the OS you were using previously. I stopped upgrading at Monterey and its been fine.

Also, if your computer is not one of the new M1, if it came with an OS version earlier than Sonoma, you can keep both OS. Keep Sonoma and add the earlier version that worked with the QBDT version you have, like 2019 for example. 

That way you can switch between the 2 OS, use the earlier version for QB and the newer version for everything else.

Google how to do this. 'How to install two versions of macOS on a Mac'
