When starting a game in which the steam online subsystem is installed, I get this error: app Error called: Assertion failed: isValid() [File:C:\UES\Sources\UE_5.2\Engine\Source\Runtime\Core\Public\Templates\SharedPointer.h] [Line: 1109], and this error occurs due to the fact that my cs servers are working in parallel, and I would like to know the solution to this problem
