Remove all of the mods you have installed. Delete all .xtbl, .str2_pc, and .asm_pc files in your game's folder, or just delete everything there (except the subfolders) and verify integrity in Steam to redownload the ones you need.
On the other hand, if you did successfully remove the mod, but you can't load a specific save without crashing, then i guess you'll have to use a different save, start over, or keep using the mod.
Finally, i'd like to point out that you previously said that your game started crashing after you installed several mods, not after you removed one.
