You have to make sure that you totally replaced the previous animations you downloaded in case it was those that were causing the crash. So make sure you replaced both canine & feline if those were both changed. Make sure both replacements or any replacements are listed as compatible for 1.17 version of the game.
If the crashing has continued then its likely something else. Consider what other changes you’ve recently made in your game. Example have you installed any other sorts of mods? Anything from items to markings mods could be causing the crashes. If you’re working off several different mod changes then you’ll need to go through them one by one to figure out which is causing the issues.
