The game crashes more frequently when I activated more than one mod and activated all experimental gameplay

I opened up Minecraft and apparently when I turned on experimental gameplay after adding more than one mods in. It frequently crashes every time. I tried opening back up and every time I click on the world it crashes the game causing the world I created to be unplayable. This happens after I updated Minecraft to 1.17.30 which is now. Is there a way to fix Minecraft world with more than one mods on and experimental gameplay. If so then fix it.
