I am having the exact same issue. I get the directory name is invalid. This is the 6th drive I have mapped. The other 5 work fine but they are marked as read-only. This drive is not.

I am using Cloudberry Drive to map an azure storage account. The issue moves to different folders when I restart the service.

I changed the mapping to read-only and I could get to every folder. I changed it back to RW and I can still get to every folder in my first few tests. I don't trust it though. I am hoping you found a solution in the last 18 days.
