Im on 3.23 which is latest, and is working here.
(that said, I was on 3.22 before, and didnt have any issues)
Id probably try a different sd card , see if you get the same behaviour.
also try using a new project see if you get the same issue i.e. detemine if its anything related to that project.
So, I know this doesn’t really address the key problem… But I think this is one of those cases where having a sd card reader and using it’s utility is a worthwhile work around… I don’t know why it’s not letting you save as… I’ve never seen that behavior before… but if you did it with an sd card you could make a copy of the file, rename it on the computer and then make edits to that copy…
