Ledger device: UNKNOWN_ERROR (0x6a82)

[memowete]

I tried all of these resest/reinstalls but still get the same error.

I had the same issue. I am not a tech person, however, reading here and elsewhere I figured to clear the Ledger Live Cache first, (Ledger not Connected). Navigated to Settings, Experimental Features, Developer mode - On. Navigated to Manager and connected my Ledger X to verify. Then clicked on Accounts +Add Account. It scanned my devise/ Blockchain and revealed my missing addresses. Can open new accounts now also. Go back to Developer mode and switch off. Hope it helps
