Relevant logs:

"Exception while invoking method saveSettings 'TOTP Required [totp-required]'"}"

Start with the Administration → users edit flow and the server-side saveSettings method mentioned in the report. Reproduce the issue with 2FA enabled and inspect how the 'TOTP Required [totp-required]' response is handled. Done means editing a user opens the one-time-code prompt in both the application and web interface instead of showing 'Undefined' or a dark screen.
