If the issue persists, please reply with an updated MSINFO that reflects the changes made.

I got the same generic runaround to uninstall my CCleaner and Sound Blaster software. They also asked me to boot my computer up with nothing running in the background. Both of these "fixes" clearly did nothing and they don't seem to get that this is a TF2 bug on their side, not hardware related.

I just got a response from Steam Support (took 3 days). They asked for a diagnostic report of my computer, so I sent that off to them. We'll see what response I get on how to fix the issue. I'll update here as I know more.

What bothers me is I sent Steam Support and the TF2 Development team structured, detailed emails of the issues, the dump files, etc and I haven't even received a response and that was 3 days ago. You'd think with the number of people having this issue I'd at least get a response that they are working on it, but nothing. Very disappointing customer service.

My computer specs

8000 Hours TF2
Did Matchmaking Beta
Was as high as Rank 9 in Matchmaking
Very few binds/scripts
No custom HUD
Custom Hitsounds

I've completely wiped TF2 and Steam from my computer and tried a fresh reinstall of both which did not work.

I tried logging onto my other computer and booting on that, it also crashes.

My main computer can run both of my alt accounts and will boot the game.

I have tried to delete the item schema files, have steam cloud off, and reverified the TF2 cache which also did not work .

I'm getting the same exact problem now tonight and I've never had it before either. Same issues, I reinstalled a fresh copy of Steam AND TF2, verified cache and files.

Works on the same computer with my alt as well which is why it's so perplexing.

I'm beginning to think it has to do with us being high ranked in matchmaking? I know that sounds crazy, but that is the only common denominator between all of us having the issue.
