You can try this: Advanced > MicroSD Card > Export Wallet .... Maybe the problem is the skelethon wallett. You can check also you pip3 dependencies

Why not use air gapped with micro SD card?

Thanks, 

Most of these I've checked. The drivers could be a possibility, but I think its likely because I'm using Mint. There might be something I need to change in the conf file.

I'm using a Coldcard HW with Sparrow on Linux (mint). I'm getting an error msg:

"Could not open client or get fingerprint information"

Any ideas how to fix this?
