When logging in to my M1 MacBook Air, 12.3 Beta 1, I find from 1 to many alerts, tiled down and to the right, all with the same error message "The file can't be found."
"The file can't be found."
I'm seeing the same after upgrading to 12.3 beta 1 on 14" MacBook Pro M1 Max. Additionally, sometime I also see an empty narrow Safari window and several of these "The file can't be found" popups. The safari windows doesn't always show up though. I haven't been able to determine a pattern.
Also seeing the same. Are you running Better Touch Tool? That's currently my front contender while trying to find what's causing this.
I'm also seeing this since the 12.3 beta and yes I have BetterTouchTool - haven't been able to isolate the cause yet though.
#Update - this has been fixed in the new alpha for BTT https://community.folivora.ai/t/the-file-cant-be-found/25868
