I resolved my issue by moving my project folder from (using the warning file as an example):

D:\GameDev\Unreal 5 P4 Workspaces\sam_TheProject\TheProject\Plugins\AdvancedSessionsPlugin\AdvancedSessions\AdvancedSteamSessions\Intermediate\Build\Win64\x64\UnrealEditor\Development\AdvancedSteamSessions\SteamRequestGroupOfficersCallbackProxy.cpp.dep.json

to a shorter…

D:\Workspaces\TheProject\Plugins\AdvancedSessionsPlugin\AdvancedSessions\AdvancedSteamSessions\Intermediate\Build\Win64\x64\UnrealEditor\Development\AdvancedSteamSessions\SteamRequestGroupOfficersCallbackProxy.cpp.dep.json

The original path was under 260 characters which the warning was telling me it was over…so that really isn’t making sense to me…that and why is the path an issue in 5.4 but not 5.3…BUT its working and compiling now. Thank you 3dRaven.
