Yes, I've sent this to support, but after three days without a response I figure I'll give it a wider airing, perhaps someone else has an idea or two.

I've been experiencing problems with DOS2 ever since he official release. As a KS backer I had access to the pre-release versions and did not have any issues at that time. I'm pretty upset that I've bought the Collectors Edition, but cant even play the game! I've provided as much detail below as possible.

The Problem
The problem I am having is the game locks up/freezes everytime I play it (after I arrive on the island), usually usually in under 5 mins, though I have played as long as about 10 mins. It usually doesn't lock up until I have left the boat and landed on the island, but once at that point of the game it is constantly crashing.

This lockup is extreme, the computer becomes completely non-responsive, to the point that I have to force a power off and reboot. I've noticed that the lockup happens in three distinct stages. (albeit these happen quickly one after the other, and no matter what i try it always progresses)

The Symptoms
1) The mouse doesn't respond to a click (could be anything, opening a character sheet, closing the inventory, movement, attack etc) - mouse can still move for a couple of seconds then....
2) The mouse cursor changes to a windows 'waiting' cursor, animated.... for a second or two, and then...
3) The mouse cursor locks up and its animation freezes.
Game music continues playing indefinately. I have left the computer overnight in this state and it didn't recover, but the music kept playing.

I cannot access ANY other computer command. Alt-Tab, Ctrl-alt-del dont work, Caps and Num lock keys dont turn on/off. Any monitoring (such as Windows resource monitor or BIOS CPU heat/Fan monitor) stop updating their display.

Troubleshooting
This has been going on since release, and I have tried a LOT of different things. None of the patches have made any difference.
• Updated motherboard BIOS Firmware
• Updated system drivers, tried both legacy and latest video card drivers
• Removed ALL USB peripherals other than mouse and keyboard
• Removed Virtual USB device (Synology) - uninstalled and removed from device manager
• No problem devices in Device Manager
• Deleted profile and all save games and started from scratch
• Turn off cloud syncing
• Turned off auto and quick saves
• Uninstalled and or quit other programs that may have been running in background such as Discord, A/V, printer management, Adobe cloud, Dropbox etc etc

I have run system monitoring utilities both Windows Resource Monitor and Gigabyte's mainboard utilities and monitored CPU , Memory etc. No spikes in activity, CPU usage normal, temperatures normal, fan speed normal, hard drive access normal.

Event Viewer shows NOTHING. The full lockup means no events are being written to log. Also no Crashdump files are being created.
