invalid project file

[D300]

Hey,
maybe its a macos thing but sofar i couldnt figure it out.. i´m on UE5.4 .
i generated a xcode project, built it, opened the .uproject and had an error pointing to "using files of previous version" ( pic attached )

if i press OPEN ANYWAY the log states:

LogProjectManager: Error: Failed to open descriptor file ../../../../../../Shared/Epic Games/UE_5.4/../../../usrname/Documents/Unreal-Projects/unreal-audio-dsp-template-UE5/UEAudioDSPTemplate.uproject
LogGenericPlatformMisc: Warning: MessageBox: Message : Failed to open descriptor file ../../../../../../Shared/Epic Games/UE_5.4/../../../usrname/Documents/Unreal-Projects/unreal-audio-dsp-template-UE5/UEAudioDSPTemplate.uproject

LogInit: Warning: Could not find a valid project file, the engine will exit now.

why is this project file not valid then?
