WSL 2 (Docker, Ubuntu) Cannot Run if DNSCrypt is Running #500

Docker using WSL2 backend crashes upon startup when DNSCrypt Windows Service created by SimpleDnsCrypt is running.

This probably has something to do with port 53 being used by DNSCrypt

I am hitting this same issue with WSL 2. For me it is Cisco Umbrella Client, which must be using dnscrypt-proxy under the covers. This only happens to me if I try to use it with both WSL 2 and Hyper-V at the same time. I got it working with WSL 2 alone, and then it broke again when I put Hyper-V back on.

I have the same issue. I want to add that changing dnscrypt-proxy service to listen on 127.0.1.1:53 doesn't avoid the issue. It needs to be disabled completely followed by a reboot to allow WSL to work.
