Hi @Wertandrew

Just done an upgrade to 38.11 on my PC

The Windows Winver command gives Version 25H2 (OS Build 26200.7171) has got same error as your pc

  1. After the Version 25H2 (OS Build 26200.7171) upgrade, the manual virtual memory pagefile was deleted during the Windows upgrade.
  2. Added the Virtual Memory pagefile of 32GB
  3. How to add a 32GB page file to Windows 11
  4. Restarted PC and can now run UEFN and Microsoft Edge/Chrome together and even start Fortnite Creative as well

This gave the impression that it was the UEFN upgrade, but it was the Windows 11 upgrade that caused the problem.
