Animations are freezing at the start/end

Im making a boss fight with 4 different moves. ive gotten basically all of it done, and i will be ready to publish once i fix this one animation bug. the bug seems to happen mostly when the boss lands the “throw” move, where he dashes at you and if he hits you, he will grab you and throw you. the animation will then sometimes just freeze at the end of the throwing animation. So far, i have made sure that i am not calling 2 animations at once, and making sure to stop and delete animations before starting another. ive also looked at other posts for solutions, but most people who had a similar problem just didnt get an answer or the bug fixed itself somehow. does anyone have any idea what this could be and how i could fix it? ive been stuck on this one bug for a couple of weeks now and could really appreciate some help.

also its not letting me put a video unfortunately. theres nothing in the console either

okay i was able to get the video working
