Hey all
Glad you're all keeping the thread alive...
Some news! I also uninstalled gameservices using a PowerShell command, as well as all other Xbox related packages, and so far I haven't had a crash since last Tuesday. BUT (and it is a big but) I've been off work and so have only rarely been using the computer. First full day of heavy usage today, though, and so far so good...
Confusingly, I have tried this method previously but it didn't work, so it's probably worth mentioning that this time I actually did a full fresh reinstall of all the Xbox packages (games services, game bar etc) before finally deleting them through PowerShell. Not sure if this would have made any difference, but thought I'd mention it.
Here's how I deleted everything:
I'll keep you updated...
