Hello,

Since few days I intermittently (at the beginning, then became more and more persistent) get this error while checking out a repo with submodules rescursively. The strange fact is that it was running ok, nothing changed. I can checkout the repo from anywhere else outside GH action, only happens on Windows runners (2019 and also latest)

this is the configuration:

jobs:
  build-windows:
      runs-on: windows-2019  # or -latest

      steps:
      - uses: actions/checkout@v2   #  v3 makes no difference
        with:
          # Fetches only one commit
          fetch-depth: 1
          # builder private sshkey
          ssh-key: ${{ secrets.ACTIONS_DEPLOY_KEY }}
          submodules: recursive

and here is the error I'm getting, please notice that it is not the same submodule failing but one between many, and it happend randomly but I'm having increasing failures.:

fetch-pack: unexpected disconnect while reading sideband packet
 Error: fatal: early EOF
  Error: fatal: unpack-objects failed
  Error: fatal: Fetched in submodule path 'deps/submodulename', but it did not contain <commitsha>. Direct fetching of that commit failed.

this commit sha exists for sure. appearently no outages happened. I've opened a ticked into GitHub but they redirected me here.
if could be of help this repo has submodules which has submodules, but the one failing most is a submodule without nested submodules

• Reproduction Steps
  go to Actions -> run workflow

Any tip would be appreciated, I'm stucked.
