Looks like you used a version higher than 3.3.0 for Docker (or accidentally updated once it installed). See this thread:
I had this issue in version 3.3.3 of Docker, but once I uninstalled, rebooted - then re-installed 3.3.0, it worked after that. Someone else also confirmed that this works (see bottom of the github page).
Make sure that after installing 3.3.0 of Docker Desktop from this page, you do not upgrade any further.
Hope that helps
All the best!
