I can confirm the problem and the fix.

I have Nine Windows 10 32bit system all running 20H2 (Home and Pro).
On Monday night I got a MB popup that there was a new version. Since I do not have MB Beta updates turned on I assumed it was a fully tested and stable version so I pushed it out to all my systems rather than wait to the next day when I would have Patch Tuesday to contend with.

Last night I noticed I could not see a machine on the network but i disregarded it as it was late.

This morning I found I could only see 4 our 5 PCs in networking. Thinking it might have been a Windows update issue from yesterday I uninstalled a WIndows update on a problem machine...Did not make a difference. I then reinstalled networking....Did not make a difference.

Then I searched the issue and found others in other forums were having similar problems and one person had said they traced it to........Malwarebytes.

So I came here....And sure enough others were having the same issue. One person had said they had turned on BETAS in MB and did an update and that had resolved their issue. So that's what I did. Turned on BETAs for MB on all machiens and then did the update which did infact download after that on all nine systems. After that some PCs reported needing to either restart MB or needing to reboot. I rebooted all NINE systems and after reboot I can confirm all NINE systems can now see each other again in Networking.

So I also confirm whatever patch was pushed today with BETAS fixed the issue. I have turned BETAs back off. Regards.
