Stuck booting forever after several successful boots

[laotze]

Hi, I recently installed and ran SheepShaver for the first time on my M1 Macbook Pro running Monterey 12.7.4. I set up Mac OS 9.0.4 via SheepShaver without a problem following the steps on the wiki guide. Everything seemed to be working fine.

However, after a few boots something has stopped working. I can’t get past the smiling Mac icon startup screen; SheepShaver hangs there forever. Force quitting and restarting hasn’t solved the issue. I didn’t change any system or SheepShaver preferences prior to the problem, so I’m not sure what could be causing it. I realize this is a vague issue, but does anyone have an idea what it could be?
