I have read through the other similar issues, I have tried older loads for fabric, etc. but my mods require the most recent version.

Fabric Loader 0.15.6, API 0.95.4, Optifabric 1.14.3, preview_OptiFine_1.20.4_HD_U_I7_pre2 work just fine without crashing.

the architectury incompatibility was also reported in #1374

also for future reference, it's a good idea to share log and crash report. See this to learn where to find them.

Thanks I appreciate it!
