I can't create a wallet on 2.0.1

[chocolatebarantlion]

Hello,

I just updated Specter from 1.x . When I opened the app, it has lost the connection to my Bitcoin core, as well as my Ledger wallet, but not the keys of Ledger themselves.

I was able to connect Specter to my Bitcoin Core again no prob, but when I try to create a wallet, I get this message :

Exception
name 'RpcError' is not defined
[Back to the main page](http://localhost:25441/welcome/)
Details
version: v2.0.1
Traceback (most recent call last):
  File "cryptoadvance\specter\server_endpoints\wallets\wallets.py", line 139, in new_wallet_type
  File "cryptoadvance\specter\rpc.py", line 503, in fn
cryptoadvance.specter.rpc.RpcError: Request error for method listwallets(): Method not found

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "flask\app.py", line 1523, in full_dispatch_request
  File "flask\app.py", line 1509, in dispatch_request

  File "cryptoadvance\specter\server_endpoints\wallets\wallets.py", line 140, in new_wallet_type
NameError: name 'RpcError' is not defined

What should I do to solve the problem ?
