Logic Pro 10.8.1 won't open a window

Nothing useful. The settings window can open, and I can change the settings. I tried resetting everything and changing the core audio, but nothing helped.

I guess some script in the software is looping. It takes around 99% CPU all the time. It doesn't look like a memory leak, because the RAM usage is not changing. This could be caused by some files which would have invalid values. Someone who had the same issue had to reinstall the system and Logic Pro started to work.

I also created a new user, but it doesn't help.

@Pancenter thank you for the suggestion, but It doesn't work.

You can see on the 2nd image, that the option is greyed-out.

Here is a spindump if it helps.

There are a few cases on the internet. Usually, people spend a lot of time with Apple support, and in the end, they have to reinstall everything. That is not an option for me at the moment.

Till this is resolved, I will just use Garageband. In the mean time, I tried the following things:

• Reinstalled Sonoma (without clearing my data)
• Delete files mentioned in this Reddit: https://www.reddit.com/r/LogicPro/comments/11ovopl/comment/jlv7313/

Nothing worked for me, but maybe you can try if it helps you.
