Can't Open IntelliJ on MacOS Tahoe, Deadlocked
I've seen other community posts, but I'm having a bit of a unique issue. I'm getting a deadlock trying to start up. My company just forced us to boost our MacOS version, and I upgraded to the latest IntelliJ after that: idea-2025.3.1-aarch64 . After installing that, I try to start IntelliJ, and it loads up the 4 projects it had open last. At this point, it displays the little bar at the bottom to get a Thread dump, and CPU usage goes to 1000% pretty quickly.
I've already tried adding ~/Library/Application Support/JetBrains/IntelliJIdea2025.3/idea.vmoptions to override the default set (maybe IntelliJ isn't picking it up because I didn't have custom VM options prior?)
I also have MacOS Stage Manager disabled

This didn't fix anything unfortunately. Anyone else seen this and know of a way to fix?
If someone from the IntelliJ team needs a thread dump, I can provide one. I just don't know where to open a ticket.
