Hello. I've recently begun experiencing a very annoying 'bug' to put it that way.

The problem is; when i try to apply a texture pack, it simply won't apply. When i choose a texturepack and click 'don', i get taken back to the regular 'esc screen' without the texture pack. For further notice; this doesn't seem to be happening when i put on new packs. but if i close down minecraft and then open it up again, then i have the same problem with the texture i just had on before. Also, if it helps; i was playing in 1.12 before this happened, so that might have something to do with it. I am using the correct version for specified packs, and i have absolutely no problems with packs in the past.

I really hope this can be fixed as soon as possible, since i really don't like the default textures.

Also, this is my first thread, since that is clearly of relevance to the topic at hand.
