Multicam sequence lag, playhead lag, everything lagging in beta 2025

On a powerful system, I'm finding a simple multicam sequence (attached to lores proxies) really lagging and difficult to edit. Playhead doesn't move. Track forward tool takes 20 seconds to complete. Making simple edits freezes for a few seconds before completing. Premiere as a whole is becoming a lot less stable in my experience for any longer form (meaning 20minutes or longer) sequences. I keep updating hoping problems resolve but it all feels less stable. Is Premiere going the route of Final Cut X? Thinking of returning to avid to be honest.

I've done every reset, cache dump, proxy creation, in the playbook and nothing improves. I'm nine years into this software.

I've written other posts with no response from adobe.
