When trying to launch optifine, the game crashes immediately and i get this error: Exit code 0. This hasn't happened before with the previous launcher versions (before Feb 24th 2021), but when I tried today (Feb 24th 2021) it just doesn't work. When i use the normal (unmodded) version of minecraft, the game launches as normal.

OptiFine issues aren't tracked on the bug tracker, they can be reported on sp614x's github page.
Thank you, it worked.
If you're on a mac, go to settings in the launcher and uncheck use beta launcher. Restart the launcher and it should be able to run.
Thanks Henry for providing some assistance here.
Mojang does not develop OptiFine so we can't fix this bug. Either follow Henry's fix and/or report this to OptiFine developers.
We've done a minor tweak to allow OptiFine to still work as before. Update should now be available to users that have opted in for beta versions of the Launcher
OptiFine has released a fix that also fixes this
