I am using a texture pack (Chroma and Zig Zag combination) and when I open my inventory in creative mode, and then want to click on the Decoration or Search tab, MC crashes (it shows items until the Iron Trapdoor, but everything after is not shown and the client closes to desktop). That did not happen before today's update.

In survival it works fine without crashing.

I wondered if it is the missing bed textures, but usually when there is no alternative texture they just display the vanilla textures instead.
I am new to Minecraft, so this might not be an actual issue with the game, since it works in Vanilla, but I'd love to be able to use my texture packs like the last two weeks.
