Thank you!

Hey @vivekpkd!

When the editor freezes and you open the task manager, is Unreal using a lot of memory? Depending on the volume or how large/complicated the files are it may be that Unreal is using up all the resources it can to import the animations.

Any additional specifics or info you provide may go a long way in solving your problem!

This is an old topic, I know. I just wanted to vent my frustration. I am working with 5.3 to keep my FAB projects somewhat backwards compatible. But - The editor is very unstable. It seems to freeze a lot, and I have absolutely no clue why. You at Epic are probably not aware of it because no crash report is sent. But I tell you: I had literally hundreds of freezes and I call myself a very experienced Unreal Engine User.
So, shedding some light into this would be appreciated.

So… I slowly get an idea what the issue is. It looks like any little error in any blueprint you have may cause it. I had an empty array in a function, and it spilled out an error message in the log file. So, I put a check “is valid index” and then the freezing stopped.
Sure, it’s my fault in a way, but I rather have it crashing then freezing to be honest. It’s a strange way to communicate an error by just let it freeze randomly. Anyway - check your log files.
