CTRL Z " DELETE" stops working

Has anyone experience that sometimes the Undo ( Mac) stops working? Then I have to relaunch SB pro. This happens couple of times a day and no idea how to solve it.

I am having a similar problem where Zoom in and zoom out doesnt work fully.

It will zoom in till a certain percentage and then stop but can zoom out as much as I want.

This has happened a couple of times at different percentages. I have tried restarting several times and then suddenly it works fine.

Super frustrating.
