The game created a log file that says what went wrong. It's in %APPDATA%/.minecraft/logs if you're on Windows. Attach the file named debug.log (if there are multiple, attach the one created most recently), so we can see what the actual problem is.

I've reported the issue to them. https://github.com/qouteall/ImmersivePortalsModForForge/issues/177#issuecomment-718095610

It sounds like you have spawn area protection enabled. Have you OPed yourself?

Uhhh... that's a weird package name. It's Immersive Portals, not "Hiding In The Bushes"

First off, you have the MixinBootstrap mod. Remove it, as Forge now packages Mixin natively, and that mod will just cause problems. Second, hiding_in_the_bushes is broken.

You don't have to uninstall Java 15. Once Java 14 is installed, it will take over, and the Java 15 install will be effectively dead. You can go into the folder where it is installed and manually delete the files if you desire

Can you try updating to the latest Forge? You're running 34.1.0, we're currently on 34.1.33.

A PR was just opened that should fix this: https://github.com/MinecraftForge/MinecraftForge/pull/7446 Keep an eye on that, and we'll let you know when the fix is pulled. Thanks to 7

This function is not renamed in the default 0514 mappings, but exists in 0723 and onwards. You need to update your mappings. To do so: Join the Forge Discord server: https://discord.gg/UvedJ9m Right click the forge-bot#9014 user, and click Message Send the command !mcpv to it It will respond something like this: To update your mappings, enter the build.gradle file of your mod, find the line starting "mappings channel" and replace it with the one the bot gives you. You will need to start a reimport of the Gradle project, Eclipse and IDEA will tell you how to do this upon saving the file. Once the import finishes, the name will be available.

Apologies, i meant UTF-8 BE, the default encoding of most modern text editors. There are well known problems in the standard Java libraries with reading / decoding these from a file on disk. You're right about all the rest though

Try deleting the whole C:\Users\bbrin\AppData\Roaming\.minecraft\config\ folder.

It sounds like mc itself is null. This happens when you refer to the Minecraft.java class from within server-only code, as it does not exist on the server. Do you have a World reference with which to check world.isRemote, to ensure that you are on a client and mc is a valid class?

That repository breaks several copyright and EULA laws and has been reported numerous times. Github's inaction does not make it okay.

Note the Minecraft End-User License Agreement: That link breaks the Minecraft EULA/TOS, and is most likely very illegal. Do not recommend this in the future, or there will be worse repercussions. The actual fix for this problem would likely be to change the encoding of the language json file. UTF-8 BLE does not encode these characters well, but the game is equipped to handle more sophisticated encodings. UTF-16 should work.

compile fg.deobf("blank:filename:fileversion") should do what you need. Make sure the libs/ is added as a flatDir repo. The blank is needed, but it is ignored. Filename and fileversion are both taken from the actual name of the file, made by turning the last "-" character into a ":" - this usually means the typical "modid-1.15.2-1.0.jar" file becomes "blank:modid-1.15.2:1.0". This creates a maven coordinate, which ForgeGradle uses to find the file. It will likely not work without this.
