Bug in 3.6.0? Win10: "docker builderx create" creates an inactive instance

[ChrisKuBa]

Hi,

after getting some problems with Docker Desktop for windows, I try to reinstall and restart Docker Desktop.

The main problem is, that the builder instance doesnt run anymore.

All works fine before the crash of Docker Desktop. Also with buildx.

Currently I build ever "arch" separately with the default build instance.

Hope someone can help me with the error
Error response from daemon: invalid mount config for type "volume": invalid mount path: 'C:/ProgramData/buildkitd/.buildstate' mount path must be absolute

Thx

A simple downgrade to version 3.5.2 solved the issue. Using my own and existing build instance. without a problem.

This was fixed in #751
