I took a look at your save data and everything seems alright. It all works fine on my computer.
Are you using the 64-bit version? If you accidentally downloaded the 32-bit version at some point that may be messing it up, unsure. The 32bit version folder is called "vTuber Kit version (32Bit)" so just double check that.
Another possibility could be maybe the custom images got erased? open that folder again where you got the save data, then go into the CustomImages folder and make sure you have images with all of these highlighted names. (ignore the fumos)
If neither of those things helps, can you send me a video of you showing all the issues? Like a minute or so recording of the glitches so I can better understand. I may have to try sending you a special build with error logging or something to figure it out. But all your save data seems okay from what I can see.
