Issue with 2017 G RAID since last OS update

Hi there,
I ran my latest Mac update a few days ago (Monterey 12.3.1 (21E258)) and since then my 4tb G RAID USB (bought 2017) is now apparently read-only. I can open it and view files, but cannot write anything on it (I use it for video editing). i get various error messages - but in my software I get "“Project Name” is already in use by “xxxxx” on “xxxx-imac.local”. I have tried to unlock it using the icon on the drive info in finder, but this doesn’t seem to do anything?

Has anyone else had this problem? If so, any fixes? Apologies if the problem is obvious - I’m not especially techy and do lose track of the various zeitgeist issues etc.

Hopefully I won’t lose anything on it? Using it in RAID 01, I did not think I’d have to backup my backup, so to speak?

Thanks,
