Did you ever end up trying it without those plugins installed to see if you had the same issue?
Other than that, we’ve been unable to reproduce this here, and it leads me to believe that there is some underlying conflict with the PC itself. You can try reinstalling the engine, verifying your engine, trying a different version. Let me know if any of those things help. I’ll continue looking for further solutions in the meantime.
Also, do you happen to be using Cyrillic symbols at all in the computer name or file paths?
