I've researched this multiple times and seen other reports going back at least a couple of years across many versions, bottom of this post are a couple of examples. Whatever problem I'm having, I can reproduce it across all of those versions.
Symptom: app hangs very frequently, often multiple times per minute, but sometimes less often and I can start to get some jobs going. As a sample of what this looks like, here I am simply switching tabs in the settings, and it hangs halfway while drawing the screen, often sitting here for 10's of seconds.
I had not looked at the logs before this moment but have attached %appdata%\cura\stderr below.
Have attempted to uninstall and reinstall (and different versions). I think I've tried it with a clean profile, but I know I have tried it w/o using my ultimaker cloud backup. I suspect something in my profile is causing the issue, but it's not clear at all how to determine what, if anything is causing the hangs, or what I can do about that.
Perhaps someone more familiar with the logs can have a look? TIA
