Docker for Desktop displays “starting …” and does not start

When I start Docker Desktop for Windows from one day, it keeps starting and does not start.

Is there a solution?
Also, is there a way to back up docker volume data in this state?
I want to retrieve the data somehow. …

It uses Hyper-v Manager.

Please let me know if you have any other information you need.

I have the same issue on MacOS 11.6. Restarting the app and computer didn’t help. My next guess is uninstalling and re-installing.

I’ve tried reinstalling, but things haven’t changed. …

By the way, this is booted using Hyper-V.

Docker’s vhdx file is over 400GB.

Is it possible that the amount of data is large and timed out? Is there a way to increase the timeout seconds?
