Animate crashing or running insanely slow when I leave a symbol or try and adjust the stage size.

I'm a 2D animator for a game studio and the last two characters I've worked on have been like pulling teeth by the end due to an issue I don't understand.

When I drill down deep into the symbol structure of the character (a vehicle with a driver) trying to leave the driver's face symbol will cause animate to freeze for about a minute. It never crashes, just takes forever to get back out. This doesn't happen with all the symbols but it is impacting my day job a considerate amount. I also get a hard freeze that I have to force close animate to when I am adjusting the stage size for the final export of the sprites.

Is the file too large? Is there a cache of files that's filled up somewhere that is causing this? Is this software actually just made of duct tape and beans?

File Specs: 481 items in the library, 977 frames of animation, 3.5mb file size, composed of lossless image assets from a photoshop PSD. Adobe Animate Version 24 Build 305.

Computer Specs: AMD Ryzen 7 2700X, 32.0GB Dual-Channel DDR4 @ 1066MHz RAM, 4095MB NVIDIA GeForce RTX 2070 (EVGA), file running off a 1TB SATA SSD.

Side problem: Animate has started importing PSDs improperly where the "asset" folder is stored outside of the PSD folder so it ends up making several copies of the "asset" folder and then the PSD folder where i expect the bitmap images to be is filled with symbols I can't access to do a bitmap swap. This software drives me up the wall.
