Slow to empty trash - even in safe mode
I have two users setup on my MacBook Pro M1 Max 14" running Ventura 13.2.1. For one of them (my usual user account), it can take between 10 and 40 seconds to display the contents of the trash can when I open it from the dock - even if it's empty. Emptying the trash usually takes 10 minutes, even for a single text file. I have tried removing all LaunchDaemons and LaunchAgents from /Library; I have tried Safe Mode. I have tried Disk Utility. I have tried CleanMyMac and MalwareBytes. I have tried removing all . files in my home. I have updated every piece of software on here (including Homebrew). The other user - a backup user - works fine. No problems opening or emptying trash, etc.
I've tried almost everything I can think of. Would prefer not to try turning FileVault off; would prefer not reformatting and reinstalling.
Any suggestions ?
