Logic pro extremely laggy interface after helper tool installation

Today I launched Logic Pro X as usual, and it asked me to allow to install a new helper tool for it's content library, which I did.

After that, the whole interface is laggy as ****.


Any ideas?


Thank you!

After a long day of desperation in one hand, but community support on the other hand, I finally found the culprit.

It was an iPad app I used for Logic shortcuts called Metagrid.

It appears that the Metagrid Control Surface script I installed into Logic suddenly stopped working and caused this behavior.

I just deleted it from the Control Surface Setup and the issue was resolved.
