UE4 Freezes when adding Blueprint Class

Development Programming & Scripting Blueprint
, , , ,

While using the engine, every time I go to add a new blueprint class the engine freezes up. None of the other programs I have open freeze or are disrupted in any way. I have checked and ensured all of my drivers are updated. I have verified the installation of the engine. I have been able to do a number of other things in the engine without any issues.The freezing occurs both when the project I have open is empty and when it is already populated. I do not get any error message, I have to use task manager to close it out.

I am using Windows 10, Intel Core i7, 2.7ghz CPU, 16gb RAM, 64 bit OS&processor

edit: also have tried without programs besides ue4 running and it still freezes

also nvidia geforce gpu

some more info – when I click to create a new blueprint class, the window “pick a parent class” is created, however it does not pop up and I am unable to restore the window to view it and the rest of the engine’s editor is completely frozen immediately.

Hmmm, start by looking in to logs, there might be some hints there, you can find logs in project directory inside Saved/Logs. Frezze is usally cause of infinite loop or blockage inside flow of thread aspecially UI, therem ight be markings of that in logs, look what was happenign before the freeze

Nothing is showing up in logs for the create a new blueprint class. As soon as I click to create new class, it creates a window “Pick a Parent Class”, but that window never pops up and I am unable to restore the screen to actually open it, and the rest of the engine is completely frozen.

Any help with this?

I think, when you create a new blueprint class you should keep open your blue print editor. it solved my problem.

Mine is UE5. When I create a new BP class, it always 100% just freeze. I had tried kept open my blue print editor, but it didn’t solve my problem… :frowning:
