Minecraft will immediately crash when launched with both OptiFine and Chlorine

Describe the solution you'd like
Compatibility with OptiFine

This is not possible. Just as sodium does not work with OptiFine, so does Chlorine.
Both Sodium/Chlorine and OptiFine effectively rip out the minecraft rendering guts
and replace it with their own optimized renderers. Compatibility is IMPOSSIBLE
between these two sets of mods.

Describe alternatives you've considered
If you want OptiFine features, install OptiFine and remove Chlorine. If you want Chlorine
features, remove OptiFine.
