Since today, version 1.12.2 stopped working. I think it's due to the release of 1.15.2

Since today, everything was working fine, but now, everytime I try to open minecraft 1.12.2 I have this error: "The game crashed whilst initializing game
Error: cdo: Unable to fit: minecraft:blocks/lava_flow - size: 32x32 - Maybe try a lowerresolution resourcepack?"

Note that I don't have any resource packs, nor mods installed. I tried reinstalling the game, but the same happened. This is the full crash report:
