After this, I can't do anything else under the CiviCRM menu.

Yes this seems like a bug. Can you make a ticket at https://lab.civicrm.org/dev/financial/-/issues/new ?

Looks like it changed to ZMW in 2013.

If you have access to the mysql database you can get your site back by doing UPDATE civicrm_setting SET value='s:3:"USD";' WHERE name='defaultCurrency';
