Resource Pack Crash

While using an outdated version of the SoftBits texture pack, I attempted to reset the texture pack to the default texture pack, which caused all block, entity, and item textures outside of the UI and player model to fail to load. Attempting to put the resource pack back on resulted in a crash. I tried it once again, after it happened to see if it was a one-off event, but it was instantly repeated. 

Sorry I forgot to attach the crash report, this is my first bug report ever.

I am quite sorry, it turns out I uploaded the wrong crash report like a total dingus. I have re-created the crash in the 21w19a update, as well.
