Game Crashes after pressing the quest complete button

hello and yes before i am german,
sorry for bad english right away.
i saw the spi aki on youtube and now have it myself, BUT i have a big problem, i cant complete quests without closing the game instance and botting it up, that even happens with mod quests and no mods installed.
in the normal game from bsg i can complete them with out crashing, breaking or shutting down the game.
in spi aki i CANT do that without this 3 things, because this even happens with modded traders.

i read through the FAQ and even trough the solved threads and couldnt find a solution so i thought im the first with this problem.
because there is no error in the server console when this happends too
the mods i use

i did try without any mods just aki itself in the beginning with a complete new acc so no mods installed and i could finish 2 quest till i needed to restart the game itself again so not really (only) mod related, i did try multiple profils with mods installed and without so so yeah not mod related

well i tried multiple things but the quest thing crashes the whole game you cant even load a mag or go in the hideout.
the loading screen dosnt finish when you try to enter a raid or lets you in but you cant interact with anything even your own gun, you cant shoot throw or change mags.
thats why my solution to this is just closing the game an restarting it

well the thing is right now i updated one of my tarkovs but still have the old version on my hdd and hoped it worked but nope dosnt work anymore so i will need to look in to it to function myself

but when i get it to run i will send the logs no prob
guess i need not update to spi aki 2.1.

i will inform if the bug is still there after updating to 2.1

hope its gone

no more porblems with this since the update.
was thinking that it could be that the game was reading the wrong code or tried to read a code thats not there for it to read what crashes it.
