The first lines mentioned it: java.lang.NoSuchFieldError: seasons at bl4ckscor3.mod.snowundertrees.SereneSeasonsHandler.tryMeltSnowUnderTrees So snowundertrees is already using compatibility features for sereneseasons But this issue indicates that both mod builds are not matching (snowundertrees expecting functions from sereneseasons which are not available -> outdated build)

Does it work with a pre-configured modpack? Try this one: https://www.curseforge.com/minecraft/modpacks/boundless-journeys-scholars-and-secrets-fabric

Did you also add Chunky or Chunk Pregenerator? Start with Chunk Pregenerator: https://www.curseforge.com/minecraft/mc-mods/chunkpregenerator/files/5632173

Maybe you have to downgrade some addons, too Remove all create addons and make a test just with Create and the other mods If this works, add the crate addons one by one

cc-tweaked and Create are conflicting Try older builds of Create or remove cc-tweaked

Try different builds of these mods until you find a working combination Or just use a pre-configured modpack which is using these mods

Some Create addons are not compatible with Create 6 yet - use the latest Create 5 build

This Create build is conflicting with cc-tweaked

Keep on this thread: https://forums.minecraftforge.net/topic/155897-4704-forge-keeps-crashing/

Does it work without any mods? Just Forge?

It is a conflict between snowundertrees and sereneseasons Update sereneseasons: https://www.curseforge.com/minecraft/mc-mods/serene-seasons/files/6229152

It is mentioned below the first red block Suppressed: java.lang.NoClassDefFoundError: com/simibubi/create/api/contraption/BlockMovementChecks$AttachedCheck at dan200.computercraft.shared.integration.CreateIntegration.setup(CreateIntegration.java:23) ~[cc-tweaked-1.20.1-forge-1.115.1.jar%23429!/:1.115.1] So some kind of conflict/issue with Create

Start with adding Create If this works, add the Create add-ons one by one

Does it work without Create and all addons?

Same issue without cc-tweaked?

Did you run the Vanilla Minecraft Version before? So if you want to install Forge 1.20.1, make sure you run Minecraft 1.20.1 before (not the latest version) If you have further issues, use another Launcher like MultiMC or AT Launcher

And without terrablender?

I have no idea - maybe try older builds of Create

Did you get the latest AMD/ATI drivers from their website? https://www.amd.com/en/support/downloads/previous-drivers.html/processors/ryzen/ryzen-7000-series/amd-ryzen-5-7600.html

Remove Pehkui

Go to the flywheel-client.toml or flywheel.json in your config folder Open it and disable it: enabled = false Or change the backend from INSTANCING to OFF (refers to the minecraft version) If there is no change, add the full crash-report with sites like https://mclo.gs/

Try to install this modpack with another Launcher like MultiMC or AT Launcher Or make a test with a pre-configured modpack and use this as working base - then add new mods one by one

Start with allocating more RAM

Same issue without Ponder-Forge?

Is this the full log? If yes, make a test with another Launcher Use the AT Launcher: https://atlauncher.com/downloads Create a Forge 47.4.0 profile and start it once Then copy just the mods from the curseforge modpack mods folder to the AT Launcher
