Increased RAM usage (and crashing) when editing sequencer keyframes

This has been bothering me for some time now since Unreal 5.2 (and still in 5.5.3) and it’s been driving me nuts.
Whenever I edit keyframes in Sequencer, whether it’s using the curve editor, autokey, etc., Unreal slowly takes up more RAM when doing so, so I have to add keyframes manually to get around it. Doesn’t matter what actor (control rig, camera, lights, etc.), it just progressively takes up more memory over time (had it go from 2GB to 13GB+ by this alone). I basically can’t use autokey/curve editor as much as I want to without Unreal crashing out.

Anyone know what might be causing this issue?

This isn’t really a solution but I noticed what might be causing it. For some reason, interacting with keyframes in anyway causes the object count to increase (UObjects?) when using Sequencer in the editor. This doesn’t clear on its own without having to run the “obj gc” command, though letting it get too high means Unreal locks up entirely where I have to force close it (recently got to 16 million objects).

Please at least do something about this, this is not normal imo
