Ctrl Z causes daz to lock up
Been having a weird issue lately with Daz studio. 90% of the time when I use Ctrl Z to undo something, it causes Daz Studio to lock up. I can use the top right buttons (Minimize, Close, etc.), but nothing else highlights or opens. This causes big issues when working on a render and forgetting to save every 5 seconds in case I forget and use the Ctrl Z shortcut to undo a mistake. Has anyone else had this issue? I have reinstalled windows recently, and it was having that issue, so I also reinstalled Daz but it keeps doing it even after both reinstalls.

I've not run into this. What are your system specs? Does this happen even if you add a primitive to an empty scene, move it, and then try undoing the move?
System specs are:
Unfortunately it happens no matter what I have in the scene. Moving, posing, changing clothing, colours, etc. Never seen this issue before either.
Ok so I just wasted everyone's time. I hit Ctrl Z again, and this time, it unlocked everything. Looks like I may need to check the hot keys. Apologies.
