Hello there @ParmarManthan!
Following your log extract, the conflict can be seen in the following line:
Unhandled exception: System.UnauthorizedAccessException: Access to the path ‘C:\Program Files\Epic Games\UE_5.2\Engine\Intermediate\LiveCoding.json’ is denied.
This boils down to the live coding process not having proper rights to access LiveCoding.json, as it’s located in the Program Files folder. There are a few approaches for resolution here:
-
Disable UAC, via navigating to Change User Account Control settings (just search for “UAC” in the Start menu), and move the slider to “Never notify” (a system restart will be required)
-
Run UE as administrator (simply right click UE and select “Run as administrator”)
-
Check your active antivirus software, and either pause it for the process, or create an exception for UE
-
Re-locate your UE install to a less restrictive directoty in your system
-
If all else fails, disable Live Coding ( navigate to Edit > Editor Options and uncheck the “Editor Live Coding” option under the “Editor” tab)
