When i try playing on -32bit, it will still occassionally crash on the hero selection screen and at the cavern crawl but not all the time. I have reinstalled windows, a ddu install for the graphics card drivers, i replaced my CPU, RAM and motherboard and its still not working. I have tried installing to a different hard drive, different folders, deleting the 570 folder and i still haven't had any luck.

I am running the following:
Windows 10 64 bit home premium
16 gb 3600MHz ddr4 ram (2x8gb)
GTX1060 3gb
AMD Ryzen 7 3700X

If you need any more information let me know, hopefully we can get this fixed for everyone as valve doesn't seem to be interested in fixing it.
