Error Default Node have no parent

Good Evening,

I ran into the problem of the game crashing to desktop first when I tried to enter Shoreline with the Peacekeeper Quest "Fishing Gear" and the SV-98 sniper rifle and the multitool in my backpack.
I looked through the logs and found an error message akin to "no foldable on weapon found" linked to the SV98.

So I just thought "welp, not going to Shoreline then." Just to find out that I could not load into any map at all anymore, like I can not enter any raid at any time anymore.

From what I can gather out of the error-log it seems to be a problem with the Christmas Presents, but I am not entirely sure.

I had the mod "PityLoot" installed, but deleted it in the hopes that it would fix the issue. No luck.

Maybe you guys can help me?

A little Update:

I did a new install(in a new folder and I didn't delete the old one)with the SPTinstaller, didn't install any mods and tried to just enter any raid, the same problem persists with the same error.
