TileEntity

You can check the config of Geckolib and Mowzie's Mobs - maybe there is a way to disable some render features

Try other builds: https://www.curseforge.com/minecraft/mc-mods/geckolib/files/all?page=1&pageSize=20&version=1.16.5&gameVersionTypeId=1 Currently, you are using build 96 - the latest one that I linked is build 106 So try 97 to 105

Keep on using 21 and add the new crash-report without modernfix

Add the full crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

Update GeckoLib to this build: https://www.curseforge.com/minecraft/mc-mods/geckolib/files/4182600

Use Java 21 instead of Java 24 Also make a test without modernfix

Same issue without Embeddium?

Make a test with another Launcher like AT Launcher or MultiMC

What exactly do you mean?

Maybe the server or a java instance is still running in background - so restarting the server after the crash results in the "failed to bind port" error The crash itself points to jvm.dll - so something on your system prevents java from working - maybe the antivirus program, firewall or something else - I have no idea

Try Azul Zulu instead of Temurin https://www.azul.com/downloads/?package=jdk#zulu

Delete the forge-client.toml file in your config folder and test it again

Server and client mods are not matching - looks like the server is starting without any mods (vanilla server) Check or add the server log

Add the full crash-report or log

Make sure the used Java version is running in high performance mode: Take a look at this: https://www.reddit.com/r/AMDHelp/comments/13hmc32/amd_not_recognizing_and_not_using_gpu_for/
