Tons of issues with my new modpack

[grave remnant]

hey guys, I'ma need a ton of help with my modpack. code is 01908b8a-5183-be2d-b3fc-568a8e0f2146 and it's sitting at around 97 mods. dm if you want a list of all the mods without needing to install the modpack
issue 1. there's an error while joining. even with that one mod that makes errors more detailed, I couldn't find anything wrong
issue 2: you can get stuck climbing the ladder on the side of the ship, softlocking you
issue 3: I picked up a driftwood giant plushie and a plastic fish (picked up a needy cat as well in the same run, only 3 scraps I found) while playing solo, and for some reason that caused one of my inventory slots to permanently fill up, even if there was no item in it (the hotbar showed a scrap item was there but when holding it nothing appeared/ could be dropped
issue 4. I played solo and died, and once I was back in the ship the UI of being dead (the whole dead players to the left thing) still showed up, and the game behaved as if the day hadn't ended, so I couldn't set launch to a different moon as it told me to wait until the ship was in orbit.
issue 5. another friend who playtested said he couldn't swing his shovel. I am unsure if other usable items have the same issue, but I did notice I couldn't squish the driftwood giant plushie despite the game telling me I could in the top right.
that's all, thanks for reading ^^

also, I figured out something for issue 5. I'm confident it's an issue with all left click items, as not even the gift box opened
