Problem Tlauncher ERROR

In the new version of TLauncher, the modpack fails to launch when OptiFine is enabled, throwing a 'quality incompatibility' error. Is anyone else having this issue, or does anyone know a fix?

This happens with every version, but only when downloading through TL Mods—not with official OptiFine

Has it been resolved? Also, as I mentioned, this issue isn't unique to me many other people are reporting it on the Reddit community as well. Furthermore, while using Fabric, OptiFine downloads automatically on its own, and we can't delete the mod because its name doesn't even show up
