Describe the Bug

I am playing with the mod pack FTB University and clients crash regularly, sometimes multiple times in a row. I run a dedicated server with up to four players. The number of player does not matter for this crash to happen. This occurs when logging in but also sometimes during play. I am not sure if this is actually Flywheel itself or one of the mods and hope to find help here with analyzing the crash report.

Reproduction Steps

1. Log in
2. Crash after any amount of time. Either directly or much later.

Expected Result

No crash.

Screenshots and Videos

No response

Crash Report or Log

If required I have more logs, but they are all similar as far as I can tell.

Operating System

Windows 11. Possibly also Windows 10.

What is your GPU?

RTX 3060 lhr but also various other. I am fairly sure everyone has an NVidia in this group.

Mod Version

0.6.10

Minecraft Version

1.20.1

Loader Version

I fear my understanding is limited. I run FTB university 1.19 version 1.2.0.

Other Mods

A list is available here: https://www.feed-the-beast.com/modpacks/108-ftb-university-119?tab=about
And in the crash report.
