Windows 10: Win10 v2004 network shares inaccessible

So, apparently over this past weekend, several of my old clients PCs were upgraded to Win10 v2004, and now it appears that none of these folks can access 'network shares' from a peer-server on their LANs, and I was wondering if this is something that others have seen as well since this update...?

Prior to this things seemed to work well, but now - Well, I am at a loss to figure out what is going on. In both cases, all PCs are on the same work-group, all PCs were upgraded to v2004 at the same time, all network connections are via gigabit Ethernet, and all network connections are 'private', all PCs 'run' and have their firewall software Norton configured for a private network as well, just as it was when they were all running v.1909. I've tried as many 'tricks' as I can think of, even re-enabling SMB1 which I'd prefer to not have to do... I've verified peer networking services services.msc to be active and operable, no group policies have been made on any system, which I might believe may have caused this insofar as none were in evidence prior to 2004 update. But try as I might, I cannot get access to network shares from this "peer server". As a last-gasp effort, I'm now 'rolling back' one clients' PCs to the previous version to see how that goes, and as I wait for this to happen on three computers I came to ask this question.

So... anyone care to share a few suggestions about why the 2004 update could've caused this?

inaccessible shared files

Thanks. That's the very first thing I did. No joy.

Once you have taken ownership of the folder, the next step is to add your user account so you can grant yourself full control, as I have done here for my user account named 'Owner'.
