Error with diff in github actions

Hello!

This error sometimes appears for an unknown reason about 1 time per 10 starts.
I'm using version 5.2.0, but I observed this on version 5.1.0 as well.

I wonder if perhaps this is specific to a certain version of helm. This seems similar to helm/helm#7600 where the helm command may not be resiliant to multiple instances running at once sometimes.

I have several jobs running in parallel to each other (via Github Actions matrixes).
And most likely they are executed on different hosts.
