Enemies skipping animations and character randomly ignoring input.

[Dragonknight951]

Was playing through a run where I was fighting the first miniboss (big mace boy) and throughout the fight i was noticing some weird delays on my attacks or sometimes my character would ignore my input outright, not jumping twice when I needed it, not dashing, not attacking. And at one point he put his shield up and I went for that free damage and then suddenly a third of my health is just gone and I see the ending few frames of his aoe slam, the shield is still up, and he is now moving again as if it wasn't even there, skipping entire frames at a time. Sometimes I would even glitch through the shield but it would block damage from attacks outside of it, sometimes he would just teleport next to me with the ending frames of the leap and deal crazy damage to me, when he did his ult i just had to sit there and take most of it because I could barely move because i couldn't jump and dash over it half the time. I ended up beating Yggdrasil without taking damage despite this (first time doing it ironically, though that might be because thief and Gambler was a good combo and the weird animation skipping didn't happen with Yggdrasil) but even then i was later curb stomped by two maids who had the same animation skips and started spamming out their extra maids and their attacks all were skipping entire animations and eventually the screen-wide pain train of like 20 or so maid minions of varying types just overwhelmed my ability to survive it and I died.
I will update to say whether or not this continues after restarting the game and validating my files (all files validated successfully)
