Bridge on Apple M1 - Big Sur - Cannot create specified folder, the folder name is invalid

I am running Macbook Pro 2020 - Apple M1 chip on Big Sur 11.2.3 / Bridge 11.1.0.175.  

When I attempt to upload photos I get the following error: 'Cannot create the specified folder. The folder name is invalid, or you not have the permission to save to the specified directory.' 

I have gone into 'Security & Privacy settings' and added 'Full Disk Access' and 'Files and Folders' for Bridge. This made no difference. 

I've also created a new folder to write to, and I am the admin on this computer. Same issue. I've never seen this issue previously on my old macbook, or previous versions of Bridge.  I'm guessing this related to the M1 chip and Bridge incompatibility? Any help would be appreciated. I doubt a re-install will fix this issue, the initial install was clean.
