Hey, I was having problems launching the game, the unity crash window would briefly show up the moment I tried to launch the exe.
I tried deleting the appdata folder, nothing, tried copying the D3D12core.dll to the exe folder, nothing (but I left the copy there, just in case).
Then I renamed the D3D12 folder and it worked! Just named it "(temp rename) D3D12", since I was planning to undo it later.
So I assume the problem is with the game accessing the file inside that folder or something of the sort.
Played it through and already bought all the store items, the game looks great.
