Shotcut stops when moving on timeline

So basically the program stops when I try to move the playhead ahead. I have a project that I worked yesterday and today I want to continue. I open it up fine, can play it but as soon I try to move the playhead ahead shotcut becomes unresponsive. I have uninstalled it, old version tested, restart my pc and all. Still it freezes.

What’s in the project(4k? sd? lots of transitions?), does it do it if you create a new project and just add a new item to the timeline, what kind of pc are you using?
