Are any of you having issues with the Undo button in 7.2.3?

Both my undo hotkey (CTRL+Z) and Edit>Undo are not working. However, it is working in the history if I go back and manually click the steps. I have tried toggling the parameter on and off in the advanced menu and haven't had any luck. Trying to avoid upgrading to Fender Studio as it makes me nervous.

Any advice appreciated, thanks!
