The Unreal Engine 5 developers made a mistake with path to PVS-Studio. A Pull Request in Unreal Engine 5 has already been created. Waiting for the update.
As a temporary solution to this UA5 problem copy the PVS-Studio.exe file from the “C:\Program Files (x86)\PVS-Studio\x64” folder to the “UE_5.0\Engine\Restricted\NoRedist\Extras\ThirdPartyNotUE\PVS-Studio” folder.
