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

Make a test with another Launcher like AT Launcher or MultiMC

Looks like an issue with bclib and the mods requiring it Better Nether, Better End, Pack BE_default_endgen_fix_1.20.x.zip
