You’ve not yet mentioned whether this Windows share is on a PC you’ve been able to access via Linux in the past. Or that you might have don to that PC before this started happening.
I’ve used gigolo on occasion when SMB mounts were being uncooperative. It’s in the default repository.
I’ve been on Mint since v.15 and v.21 is far and away the buggiest and most temperamental Mint I’ve used.
And it’s still flaking out. There was an update in early April that caused my volume control to disappear at least every other day. There were dozen’s of work-arounds but the only one that worked for me was to reboot.
If I’m going to have to reboot it that regularly, I might as well be on Windoze.

I have a lot of different installs on a lot of different drives to test. I have had problems with everything above 20.0. Using 20.0 has been very stable and working well for over a year now. So far 18.3 was good, and 20.0 is good. all the other have been buggy or had driver issues.
Chasing the newest is not always best.
Up until a couple months ago, Windows and Linux interfaced just fine. I bought a faster Netgear router and I thought maybe that was the problem. But I just hooked up an ASUS router and I still have the same problem.
