preview builds prevents virus and threat protections to start

I have win11Pro, upgraded from 10 home.  I am an insider and have switched to a canary channel.  I never switched it, but now I only get the preview release builds.  

I am trying to download some trial software for my work and cannot since it "fails virus scanning."  When i checked on the virus and threat protections, i found that it was stopped.  I tried to restart it.  It would not.  

I thought, "Maybe I need to update my device," so I did.  Restarted.  I then went back to the virus and threat protections and attempted to restart them, but it failed again.  I checked my startup applications and services, and of course, virus and threat detection is supposed to start on booting.

I don't know how to fix this bug, and i need to download a trial software for work, but I need it to pass virus scanning as well.  I cannot achieve this if the service has stopped and cannot be restarted.  

What do I do?
