Error message on startup / movie render queue crashing 100% (UE5-P2)

Hi @all;

when i open up the engine (ue5p2) i get the following error message:

LogOutputDevice: Error: === Handled ensure: ===

it does not impact my work in the engine and i can render out from the sequencer just fine, but everytime i try to use the movie render queue, even with minimalist settings, mrq crashes.

can someone point me in the right direction where to look for my error?

cheers,

I’m getting the same error for my game in UE5 Preview 2. It’s slowing down my game dramatically. I’m not using a “D:” drive.

The ContainsNaN() error was caused by a blueprint that was migrated from UE 4.26 into UE5 P2.

The slowness issue was caused by an unrelated issue.

How’d you fix it? :slight_smile:

I went through every single blueprint and material and found some broken nodes that I had to fix.
