1.17.1 Pre26 crashes server shortly after start up

[OldManCrafter]

Description of Issue

I log in to the server, game comes up with not more than 4fps, time goes away, causes the server to fall about 105 tics behind which leads it to automatically shut down. I am able to play fine with optimize turned off. I’ve seen significant lag since MC’s 1.17 update and a lot of server crashing since optifine 1.17 pre 21.

Steps to Reproduce

1. Every time I log in with optifine running
2. It occurs with render distances down around 20. Admittedly my computer isn’t the greatest, but prior to the newest update, I’ve been running very smooth and no crashes.

OptiFine Version

Installation Method

Installed directly from optifine web site.

Other Installed - vanilla tweaks data and resource packs running on server and locally respectively.
