Just updated to 4.23.1 and the project i’ve been working on in 4.23 now crashes on load. Tried verifying engine, then completely reinstalled engine. Still crashes when I attempt to open the project.
Same! Just updated to 4.23.1, and when try open project - just crash.
I think I have the same problem, but I do not even have a screenshot to add b/c the Editor would just freeze, for which the only thing I was able to do is to just force-quit the computer and restart.
I managed to run the level. I think I understood what was the cause of the error in my case. This was due to too many shaders that needed to be recompiled. I just opened level after level, until the main number of shaders was compiled. And after that I managed to launch my main level - it works.
Remember it is best to continue work on your project in the same version, without updating it. There always is risk of ruining your project with Engine version update.
Hey all, same happen with me dozen of times 4.23 & 4.23.1 both the updated versions crash whenever I enable Lighting Only tab or shader complexity tab & one more thing don’t know from last 4.23 version whenever trying to build light we cant do anything in file it got stuck until rendering completes.
Do anyone also facing the same issues if yes, please revert back

Yeah I didnt think going from 4.23 to 4.23.1 would be risky. was wrong.
please explain how you got the shades to recompile by opening level? My engine crashes every time i attempt to build lighting. giving me this default pawn class error.
I would pay money for someone to fix this… Ugh. Every time I attempt to build the lighting in this level it gives me this crash about base pawn class. I then have to restart ue4, duplicate the level (as trying to open it at that point just crashes again), then delete the original level, open the duplicate to get back into the level. BUT cant do anything as it simply crashes if I build lighting.
I’ve tried the following so far, with not guaranteed enough results:
- Validate UE4 4.23.1
- Toggle off Real-time Thumbnails [Unreal Editor > Content Browser > View Options (bottom right)]
- Turn off battery boost [NVIDIA GeForce Experience > Games > Battery Boost] (I have GTX 1060)
- Try using DX12 [Unreal Editor > Project Settings > Search RHI > Default RHI to DirectX 12]
- Disable Intel Graphic Card / Make NVIDIA GeForce as default graphics
- Update Windows 10 in hopes of fixing DirectX if it is faulty (Currently on Win10 Pro Insider Preview build 18975)
- Reinstall UE4 4.23.1
- Keep the machine at Turbo mode (I’m using an ASUS ROG laptop)
But again, all of these in combination is yet to take care of the problem.
For the time being, I found that these measures help alleviate the problem a tad bit.
- Keep Unreal Editor as Window Mode (I have been using it at Full Screen Mode, so for those of you who are already using it as Window Mode, this won’t be much of an advice)
- When it freezes, try putting the machine to sleep mode first. This has helped me un-freeze the Unreal Editor, but doesn’t really help much if your Unreal Editor goes straight to crash instead of permanently freezing.
Hopefully someone behind UE4 can help us out.
EDIT: For me, Changing Default RHI to DirectX 12 causes yet different type of crashes, with Unhandled Exceptions, no explanation whatsoever.
