Manual testing steps

Manual steps are also described in the github
issue. However; I do not think that the Show native token as main balance needs to be ONt o repro the initial issue. Also no need to add new RPC from chainList;

Settings:

1. Show balance and token price OFF
2. Token autodetect ON

On main view

1. Select an account which has some ERC20 tokens in Polygon

2. Add Polygon default network

3. See tokens are autodetected and you can open the modal -> but don't import the tokens!

4. Switch to another network

5. Delete Polygon network

6. Re-add Polygon default network

7. Click Import tokens --> Wallet should not crash
