Having the Iceberg library mod (and so mods that use it like Advancement Plaques) and/or the tooltipfix mod installed together with optifabric and optifine results in a crash.

I have a lot of Mods installed so it took quite a while to find the issue, especially cause the Crash report was
"The game crashed whilst initializing game
Error: java.lang.RuntimeException: Could not execute entrypoint stage 'main' due to errors, provided by 'dynamicfps'!"
Which is a different Mod, that causes no issues without either optifabric or Icberg/tooltip installed. Hres the full Crash report:
crash-2023-08-28_17.33.24-client.txt

Note that the same would happen with other mods when you take dynamicfps out.
When all the mods that minecraft claimed provided issues were taken out it would just crash without any obvious issues and a exit code 1

The actual issue is with the GuiGraphicsMixin, it’s just further down the error report for you. Probably caused by optifine classes
