multiple resources cleanup

✗ Failing This test is currently failing.

Failed: backend-exec

Failure Output

error[KORU030]: Phantom state mismatch: 'f.file1' (parameter 'file') holds no live '<opened!>' obligation to consume here — it was never acquired or has already been discharged. Pass a value that still holds its '<opened!>' obligation.
