At some point you could try the new CPU.
The issue does seem to be software related though.
As the xinput1_3.dll (older DirectX file) appears to be referenced in the error log and dump can you try following:
In the C:\Windows\System32 folder locate the following file:
xinput1_3.dll
Right-click the xinput1_3.dll and rename the xinput1_3.dll to xinput1_3.old
Log out and log back in again.
Can you launch VR Chat?
If no effect you can rename the xinput1_3.old back to xinput1_3.dll
