Error mounting known_hosts file when starting Docker Compose application

[yohangwak]

Hi,
I get this error when attempting to start docker magento

Cannot start Docker Compose application. Reason: compose [start] exit status 1.

Check if the specified host path exists and is the expected type

I think I have correct permission

ls -la /Users/yohan/.ssh

I tried to comment out those but still get same error

I ran bin/remove and then bin/start and it worked for me

also noticed this occurs more often if i don't run bin/stopall before bin/start and even at times bin/restart

Rebooting Docker desktop resolves it as well.

just for completeness, I have been running bin/start --no-dev and then bin/start, usually works. bin/remove should be a last resort.
