A streaming error has occurred. (WOW519000322)

What worked for me was removing the Wow.dxvk-cache file which can be found in the same directory as Wow.exe. The reason I tried this were the memory access errors found in the Errors directory. I figured the cache may be stale and dxvk isn’t able to clear it before crashing.

Heading from my last 2019-11-12 00.28.12 Crash - 258.txt:
