Yet another crash report

Hello.

Since day two of the league I have issues with performance and with
launching the game.
At the beginning of the league I managed to play mostly fine,
progressing up to act 6 of the campaign. But the very next morning
when i tried to login i had following issues:
1. Game crashes right at the start of game
2. Game crashes at the two-gears animation
3. Stuck at an infinite (or at least painfully long) loading screen
4. If i manage to skip all of those issues i get stuck it the loading
screen moving towards the next zone
5. If i manage to load to the next zone, i crash at the very first encounter

My specs:
OS: Win10
CPU: i7-3770K
GPU: RTX 2070 Super

What i've tried to do:

1. Updated graphic card drivers
2. Updated windows
3. Cleared game cache in %AppData%
4. Tried the compatibility mode and ran as an administrator
5. Tried lowering graphic and sound settings as much as possible

I've also seen that switching to Dx12 helps a lot of people, so I
tried it too and had the following issues with that
1. When i try to switch to Dx12/Vulkan in the login screen, the game crashes
2. If i try to launch the game with Dx12 already setup (in the
production_config file), it just doesn't, crashes either instanly or
the two-gears animation

I've verified using dxdiag that my system is capable of running dx12
and if needed I can provide a dxdiag report.

And checking the windows event history i found this:

When trying to swtich to Dx12 ingame, i've got an error (cant provide a screenshot, since its not in english):
Can't access the file Q:\SteamLibrary\steamapps\common\Path of Exile\ShaderCacheD3D12.packed\1.dat

And when crashed loading the char:
Can't access the file Q:\SteamLibrary\steamapps\common\Path of Exile\Bundles2\Art\2DArt\Cubemaps.E.bundle.bin


Launched file check in steam, but it takes so much time to do it, crazy
Also doubt it will find anything, because i reinstalled the game like twice already
