Logic Pro wont' start after updating to Monterey

Or rather, it was updated for me. It started with hardware problems, and the mainboard was switched to my laptop. Before I was still using Catalina, but when I got my machine back from repair, it had Monterey. Ok, give it a try I thought. I restored my data from Time Machine backup.

First problem, after restoring when initialising signup, it could not connect with my appleId. And could not thereafter. After multiple chats with apple support, only solution was to create new user and start doing that.

Then. I updated all the third party plugins, which had updates. Native Instruments, Izotope, IK Multimedia and Toontrack. Also had to re-authorize some, I guess cause the different user. Then updated the UA Apollo twin drivers and firmware.

Logic just won't start. Crashes immediately. When started with control modifier key (without core audio) it did scan the AU plugins, during which several errors were thrown, but finished that none the less. Still, won't start normally. I attach the crash log here.

Is the only way to downgrade to Catalina? It did not do that when I restored the data from Time Machine, but it should be possible I thins?
