well, I decide to just cut the entire history and get the lates revision one more time.
I issue this git command,
git clone https://github.com/EpicGames/UnrealEngine.git --depth=1 --single-branch c:/unrealEngine_5.5.0
and hut the master head revision. running setup and GenerateProjectFiles.bat
the log says this.
Setting up Unreal Engine project files...
Using bundled DotNet SDK version: 8.0.300
Building UnrealBuildTool...
at least that’s a change, the download zip one says
Using bundled DotNet SDK version: 6.0.100
I am hopping this is the end of the ordeal.
I just lost the entire history of my branch that I kept for 11 years.
