Specter v2.0.1 is now so slow that I get an error when trying to look at the settings for the wallet.

Describe the bug I have a long-term wallet with over 1000 change addresses. I updated from v1.13 to v2.0.1. It takes many minutes to first load the wallets when opening Specter Desktop. Much much longer than with v1.13. If I select settings after about 1 minute I get a server error that lists the exception as 'dictionary changed size during iteration'. I have had to revert to the 1.13 app image to use Specter Desktop

To Reproduce Happens every time I try to look at settings of this heavily used wallet.

Expected behavior It should list the settings.

Screenshots none

Desktop (please complete the following information):
