Unable to load VariantManagerContent plugin on VSCode standalone Development build ue-5.3.2

Hi!, i’m unable to run a standalone development build made from vscode, but it runs without problem if i package it, or run directly on the ue editor, only the binary produced by vscode fails. The missing plugin looks like from base/core, so this seems tied to project configuration.

Im using linux (arch), followed the docs on toolchain installation the best i could: run Setup.sh, GenerateProjectFiles.sh, Cooked Content, and “refreshed VSCode project” from editor, and the compilation of the binary is correct from vscode, tried on the shooter and third person templates. I also tried on 5.3.1, and ldd shows all .so are ok.

The error message is “LogPluginManager: Error: Unable to load plugin ‘VariantManagerContent’. Aborting.” (sometimes says RigVM instead of Variant…), after it complains about not finding a file on a folder which doesnt exists:
LogStreaming: Warning: Failed to read file ‘/home/username/opt/ue5/5.3.2/Linux_Unreal_Engine_5.3.2/Cloud/IoStoreOnDemand.ini’ error.

Where i can find some clue about this?, how can i check the correct libs are being linked, the content is accessible, or that my project structure is ok?.

Thanks in advance, this is my first question here.

Output from the binary made from vscode:

Increasing per-process limit of core file size to infinity.
- Existing per-process limit (soft=18446744073709551615, hard=18446744073709551615) is enough for us (need only 18446744073709551615)

I’m getting the exact same warning and error (IoStoreOnDemand.ini and VariantManagerContent) when trying to run a built and cooked multiplayer client for my game. I am also running unreal 5.3 on manjaro linux (arch). I would really like to find a solution for this. Hopefully my reply increases interest in this post…

Im getting the exact same error in the logs of my packaged game. The game is packaged for windows not linux tho. If anyone knows the cause that would be very helpful because this is the only mention I found so far of this error.
