AE2 Fabric Alpha 3 (had same issue with Alpha 2)
MC 1.16.5
Fabric 0.11.3

I have a simple setup. 3 Energy Cells, 1 ME Drive with a single 16K Storage Cell, 1 Crafting Terminal (see provided Screenshots)

Power is not an issue since my energy cells are full or after restart getting there.

Please provide the crashlog as requested in the issue template (using the F3+C shortcut if i remember correctly)

Its not crashing.

When I hit F3+C and paste it: /execute in minecraft:overworld run tp @s -22.97 61.00 85.60 -326.06 17.25

you have to hold F3 + C for like 10 seconds

This crashed my MC.

latest.log

Do u need further info?

Hm, I didn't even know Optifine would work on Fabric.
Either way, we can't really support Optifine, sorry.
But even besides Optifine, you have so many errors in your logfile that I couldn't really help without Optifine either.

Optifine workes with Optifabric. Could u point me in the direction of some errors because im to blind to see them in the log.
