NFT wallet broken

[Amplificator]

I have somehow gotten an issue where my NFTs seems to have disappeared due to what looks like a broken NFT wallet. With the help of someone, we found out that I actually still own the wallet addresses they are in.

When running "chia wallet show" it will show that I'm fully synced and then continue to list the Chia Wallet and Pool Wallet just fine but then throws an error as soon as it gets to the NFT Wallet - this wallet seems to be.. broken for me and I assume that's why the GUI also isn't showing any NFTs?
On one machine I have also cleared databases (wallet db and blockchain db) along with config.yaml, basically clearing everything out that I can. I then resynced to see if that would have fixed it, but it did not.
I also tried setting up a new virtual machine with only Chia on it, nothing else installed and gives the same result so it doesn't appear to be a local problem on a single machine.

The error I get when running "chia wallet show" is this:

Exception from 'wallet' {'error': '3', 'success': False}:
Traceback (most recent call last):
File "chia/cmds/cmds_[util.py](http://util.py/)", line 100, in get_any_service_client
File "chia/cmds/cmds_[util.py](http://util.py/)", line 211, in execute_with_wallet

File "chia/rpc/rpc_[client.py](http://client.py/)", line 50, in fetch
ValueError: {'error': '3', 'success': False}

What I did in the weeks before this issue was to enable both DataLayer and Wallet Connect but never actually used them so I disabled both again. Days later I created offers for these NFTs but also cancelled those. I verified that the offer section reported that the cancellations had been confirmed so I know they didn't go anywhere (and as stated above, we verified that I actually still do own them).
But after cancelling the NFTs they simply disappeared from the GUI, so I assume somewhere along the line the issue with the NFT wallet happened and the GUI simply can't show them.

The GUI throws no errors, but running "chia wallet show" on the command line will result in the error above.

Any suggestions on what exactly happened and how to fix it?
