Windows 10: Strange copy/cut/paste behavior Windows 11 Pro and NAS

Windows 11 Pro Version 22H2 build 22621.2506When I copy/cut a file from my desktop PC and paste into a folder on the same desktop PC, everything goes as expected. Same for pasting into a USB flash drive.But, when I copy/cut and paste into a folder on one of my 2 NASs, I get the following popup window. I get the same message if I try to paste into an empty folder or one with other files in it. It doesn't matter which file that I try to cut/copy/paste. The file that I'm pasting does not exist in the destination folder.Any help to solve this problem will be greatly appreciated. Thanks in advance.

Cut & Paste becomes copy&paste

After booting up, cut&paste works fine. But after using my Windows 10 PC for a while, cut and paste successfully pastes the file to target location but fails to delete the source files. So effectively, cut&paste becomes copy&paste.

This happens after I've run multiple applications after a while. Normally, I'd have Winamp, ACDSee, Windows Explorer running with a few others already in the background like Bandicam, gog galaxy, etc. I sometimes run into this problem and sometimes don't
during a session of moving about my files. But cut&paste for long enough, I'll eventually run into it. I've tried to find a pattern but couldn't find any scenario that triggers this behavior. The only thing I can do is close everything and reboot. This is
very annoying.

I searched and searched and only found issues regarding copy&paste not cut&paste. At this point what can I do and is a fix in the works?

Unable to copy and paste to NAS drive

Since the last big update to W10 I cannot copy and paste files to my NAS drive. Copy seems to work as usual but when I try to paste that option is greyed out. I have 2 machines with the same problem. I use the NAS drive as my back up as well and don't
know if thats working. I'm totally computer illiterate so any suggestions will need to be simple . All I know is one minute it was working as it has been for the last 3 years and then kaput!
