Process completed with exit code 1 using self hosted runner

[nepp95]

Hello,

First of all, thanks for the action that we Vulkan Developers have been longing for :)

Problem:
After running the workflow, I am hit with the following error: Error: Process completed with exit code 1

The preceding code from the workflow it was executing before it gave the error is:

While bash is ofcourse a shell we are able to use within WSL and thus also github's hosted runners, since that enables WSL, I have not yet figured out how to do such thing myself. I am using git bash which comes with git which gets added to path. This might be relevant since before I did that, I encountered the "Bash, command not found" error coming from this action so it inevitably needs bash.
I have tried to trace where this is coming from but can only find an exit code 9 within the function being called.

Kind regards,
Niels
