What happened?

When using fabric REI for 1.21.1 (either release, as of right now this is just 16.0.762 and 16.0.754) and fabric api 1.21.1 version 0.16.5, Minecraft will boot to a white screen, crash, and report not enough memory (exit code: -805306369).

Expected output: Minecraft boots properly and normally.

What mod loaders are you seeing the problem on?

Fabric

What do you think this bug is of?

• Visual
• Recipe Lookup
• Cheat Mode
• Plugin Integration / JEI Plugin Compatibility
• Others

Relevant log output

No log output, as Minecraft was never able to start.

Anything else?

To reproduce:

1. Install Fabric Loader 0.16.5 for Minecraft 1.21.1.
2. Add Fabric API version 0.103.0+1.21.1.
3. Add REI version 16.0.754.
4. Launch Minecraft through and observe the error.

This fixed my problem, architectury was missing and it didn't tell me. Yes enough dedicated wam (ram) was available lol.
