I have UE 5.1.1 and still have this problem. Enabling Electra Player or setting the RHI to Default didn’t solve the issue for me…

switching to DX11 solves the problem, if you don’t need DX12 in your project you can switch.

After activating the Electra plugin and restarting the project, changing the settings in the source file for windows with electra solved my problem.
