I had an old UE 4.26 project that I used to work on on Windows. I’m trying to open it on Linux. I build Unreal 4.26 with no issues. But when I try to open the project, I’m first told that it was made with a different version of Unreal. It was the same version but a different platform. I don’t thank if that’s supposed to be an issue. Unreal then makes a copy each and every time. Then, after it’s tried rebuilding the project, I gives me a very long error message. I’m cutting here for space.

Please rebuild from an IDE instead.
When I try opening the project through UE4Editor through Qt Creator, I get:
The engine module is out of date and cannot be compiled while the engine is running.
I tried compiling with RunUAT like this:
/RunUAT.sh BuildGame -project=/Path/to/Profect/File.uproject -platform=Linux -configuration=Development
Every time I try opening the project with UE4Editor, it creates a new copy. It says that the project was created with a different version of Unreal, which is not true.
I tried deleting the folders Source, Intermediate, and so forth.
I tried adding DefaultBuildSettings = BuildSettingsVersion.V2; to both Target.cs files. I tried removing the last two options to the Arguments string in the file Engine/Source/Developer/DesktopPlatform/Private/DesktopPlatformBase.cpp, changing Arguments += " -Progress -NoEngineChanges -NoHotReloadFromIDE"; to Arguments += " -Progress"; and the recompiling the whole engine. I recompiled the project many, many times.
At this stage, I really no longer know what to try, short of creating a new project and slowly importing everything into it. I really don’t want to resort to that.
What can I do?
