Optifine [Mod Compat]

**What mod is causing it?**
Optifine when added to 5Zig causes the entire game to crash. The game does not even launch. When I try to launch it the game crashes immediately and goes back to the launcher with an error screen.

**Does the mod load?**
Individually both Optifine and 5Zig will load and launch. When I try adding Optifine during the install process it causes the problem.

**Does 5zig load?**
When I install it without Optifine it will load and run normally.

**Which features of the mod don't work?**
The entire game crashes so none of the features work.

**Which features of 5zig don't work?**
As said above, the entire game crashes so no features work.

**Screenshots**
If applicable, add screenshots to help explain your problem.
No screenshots as the game does not load.

**Desktop (please complete the following information):**
- OS: Windows 10 Home
- Version 21H1

**Additional context**
Add any other context about the problem here.
I have tried this with version 1.15.2 and version 1.14.4. I got exit code 0. 5Zig + Optifine does work with version 1.8.9 and version 1.12.2. I can add the crash report if that would help.

The issue describes a crash when Optifine is added to the 5Zig mod for Minecraft versions 1.14.4 and 1.15.2. Start by examining the crash report if available, then look at mod loading and compatibility code. Check for version-specific initialization or resource conflicts. Determine what 'done' looks like by verifying the mods load together without crashing on the affected versions.
