I can’t CTRL + Z to undo anything, no other tab is opened

looks like deleting Undo History is the solution, even though it’s very strange solution

nope! it appeared again. I encountered this problem only in 5.2 when working in sequencer, especially after adding animations to a SKM in sequencer

any updates on this? I’ve run into this a couple times and it’s a similar same situation.

what version are you using? this seems like an unfixed bug in 5.2
not sure if it is relevant in 5.3, I am not active right now in 5.3 because doing projects in prev versions

had this, shut 'er down, checked launcher, had a plugin update for metahuman, updated that and restarted 5.2 from launcher library, magically working again.

This is happening to me suddenly on a project I’ve had no problem with for months. It’s definitely related to Animation mode on an SK in sequencer, totally breaks undo. Unfortunately there’s no way to stay in Selection Mode to troubleshoot whether it is for sure related to Animation Mode, Anim Mode opens the second you touch a control rig track in sequencer. Anyone have any thoughts? UE 5.4.4, Windows
