[1.19.3] This happens in my modded minecraft world every now and then. Usually when I open the world for the first time, it freezes, screen goes to black, and then when it comes back it says this. Sometimes Minecraft stops responding, and then I'll force it to close and my latest.txt will say this too after a line that says "Caused by:" with the following "Can't keep up! Is the server overloaded?" a few times with the amount of ticks it's behind by. Otherwise, it runs completely normally.
I'm unsure which mod this is related to, or if this is an allocated memory issue? Does anyone know based on the title? There is no crash log, just the error spit out in the title.
