Both GUI and UI resource packs crash/freeze the game when active or trying to load it into a world

Howdy! i seem to be encountering a problem about resource packs, specifically ones that change gui and ui. The issue is that the pack appears to crash the game when loading it into a world, and when the pack is still active after the crash it freezes the game and initiates another crash. its been an ongoing problem since august and is only happening on the recent update of the game. On previous updates all the packs work that adds custom ui and gui.  I hope this problem gets fixed soon since its a bit problematic as a texture pack creator. Many thanks^^
