Additional Context

I successfully compiled a Windows version of the plugin two months earlier, so I'm assuming that my Windows build environment is set-up correctly, since I don't remember changing anything.

I have some hunches to where the error might come from:

1. some required tensorflow commit has disappeared from github as mentioned by this Warning:

WARNING: Download from https://storage.googleapis.com/mirror.tensorflow.org/github.com/tensorflow/runtime/archive/2f6de37d68a4c69e2ff9eec3cebbf1369e496940.tar.gz failed: class java.io.FileNotFoundException GET returned 404 Not Found

2. Windows is unable to create symbolic links (for whatever reason) as mentioned by this Warning:

WARNING: failed to create one or more convenience symlinks for prefix 'bazel-':
  cannot create symbolic link bazel-bin -> C:/_bzl/5laulzlv/execroot/mediapipe_api/bazel-out/x64_windows-opt/bin:

3. I assume the final error shutil.ReadError: bazel-bin\mediapipe_api\mediapipe_proto_srcs.zip is not a zip file is a result from one of the two above mentioned Warnings. Also, I noticed when recently compiling pure mediapipe in a linux environment, that the latest mediapipe requires g++ version 8 and not g++ version 7 anymore. However I'm not sure if that is the problem here, as I cannot really see which compiler is used during the build on Windows 10

Maybe the same as #549.

Is there bazel-* folders under the project root? If so, remove it.

[mgarbade]

meanwhile it is working again. I applied two fixes (not sure if one or both did the trick)

1. Used VisualStudio 2022 instead of 2019 to compile the project. To specify the version I added a system environment variable BAZEL_VC with the value path\to\my\MicrosoftVisualStudio\2022\Community\VC
2. I copied the source code from partition D:\ to the system partition C:\ which might have caused the above mentioned "symlink problem", according to this thread, quote:

Add /D to all cmd CD calls, this makes CD change drive as well as directory
