Github Action failing: Process completed with exit code 1 when installing system dependencies for R-CMD-Check

I am trying to run the use_github_action_check_standard() command from the usethis R package to check my package on every push on GitHub Actions.

The test works without a problem on Windows and MacOS, but for both Linux versions my workflow code fails before it even gets to the package code.

It fails when it tries to install the system dependencies where it gives me the error ##[error]Process completed with exit code 1.

When I look at the raw logs (below), I notice the line: Cache not found for input keys: Linux-287c850eb370edd647ed85b6fac18cbaee02effa7d01b981304dce84a452b22c-1-, Linux--1-. But I'm afraid I don't understand that error. Also I don't think this is it, because the key appears in the group above (notice the ##[endgroup]) already but the error only appears in the next group (as on the Screenshot).

Any ideas? Many thanks!

I also post my entire workflow code below.
