Premiere keeps freezing

I’ve been trying to edit a super simple video for the past three weeks, just basic cuts, no effects, and Premiere won’t work. Every time I open the project, it runs for a few seconds and then completely freezes. Sometimes it goes “not responding” and I have to force quit. Other times it stays open but nothing works. I can’t open the source monitor, can’t switch workspaces properly, and the timeline doesn’t respond.

I formatted my PC, reinstalled Premiere several times in different languages, started new projects from scratch, tried importing the old one, cleared all caches and plugins, upgraded to 32GB RAM. Nothing changes.

It’s only Premiere. Everything else on the PC works fine. The videos were recorded on an Insta360 camera, normal resolution. I’ve edited way heavier files before and never had problems like this.

At this point I can’t even take screenshots because the app freezes so quickly. I have no idea what else to do. Anyone got a fix?

I even tried rendering this sequence to MP4 just to start a new file from scratch, and if I needed to change anything later I’d just find some workaround, because it’s literally IMPOSSIBLE to work on this project.
