Failed to Load Mods

[Nickenator2370]

For some reason when I'm trying to download the modpack "Ultra Modded-Survival", it randomly pops up " Failed to load (a random mod ) etc. tropic raft/twighlight forest and it just closes itself, btw I have already tried to reinstall the mudpack and also tried to reinstall the technic launcher and still the problem remained.

Not a launcher issue. Moved to Platform Pagoda.

Well, listen to the error popup. Try contacting the modpack author on whatever channels exist (discord, the modpack discussion tab, github?). Likely to either be an issue with the solder configuration or something with solder itself is down.
