Fatal: Trailing magic number is different (0d)

Im trying to run a cross compiled (from window10) Linux Server on my Ubantu Machine but then i got this fatal error:

Fatal Error: [.../IPlatformFilePak.cpp] [Line:3919]
Trailing magic number in (.../xxx-LinuxServer.pak') is different (0d) than the expected one.

I built this with “RunUAT.bat -noP4 -pak -platform=Linux -server -serverPlatform=Linux”. So I have no idea how the pak file could be different one since they are built together.

Can anyone help me on this?

Thx in advance.
