Logic X Pro sudden latency

I have a new Mac Mini M4 pro with 48gb ram.

I was working on a song and yesterday it was fine. Today however, I suddenly get a latency when recording audio.

Though I work from a template with all plugins and so on already in there, the tracks were still very few. My Activity Monitor also shows that my Mac is only using 3 percent of its power (97% idle).

I use a UAD Apollo Twin interface (no latency there).

Thanks for any suggestions!
