I hope I’m getting closer to at least a temp solution. Posted this in the other thread.
Put in a ticket. @W1lddogg you jixed me, SOD2 started doing the same thing as well. Gears Tactics (Game Pass) and MC Dungeons (Owned) are fine though.
UPDATE: So I may close my ticket as this is starting to seem like an XBOX app issue.
So far I have just done my tests with SOD2 as it is the smaller game, however I unistalled the XBOX app and used the Windows Store to redownload the game, started it up, rebooted and lo and behold it was still working upon login. I am testing again installing it on my game drive as my C drive is dedicated to windows and I don’t want to keep games on it. Ill report back again after I get a little more testing in, and of course test MCC.
Summary: SOD2: Uninstalled Xbox App, installed to C: using Windows Store, survived a reboot with no issues. Trying again using my game drive (D:) and see if I get same results.
MCC: Pending as it is a bigger game.
UPDATE 2: So I think W4R was on to something. My install of SOD2 on D: did not survive a reboot, however, without doing anything in the store (repair/reinstall) I found my default install location in Windows Settings. It was set to D: so I changed it to C: then immediately back to D: and the game launched. Still need to do a reset and see if it bugs out again, but at the very least this might be a simpler temp fix.
Summary: SOD2: Change to D: did not survive a restart, but changing then changing back the install location got the game working again.
MCC: still pending
UPDATE 3: Does look to be Windows related NOT Xbox app or game related. A reboot borked SOD2 again, and again a quick move to C: then back to D: solved the issue. Again not ideal, but much better than redownloading anything.
MCC: Downloading now, will give one last update
UPDATE 4 FINAL: Yep, MCC was acting the same way but the trick that was first mentioned by others (also here https://www.halowaypoint.com/en-us/forums/85d779d52cfd46918b4f8b638f2e3c7b/topics/solution-found-for-mcc-not-launching-after-restart/702ec981-3934-440e-b6f6-aa92b034285a/posts?page=1#post2 )
works, safe to say it a windows issue…closing my ticket with support.
TLDR: if you have this issue and the game is not installed to C:, go into your default save location in windows settings, change from what drive you are on to C: hit apply then switch right back to the desired drive and hit apply, you will be able to play. annoying but a quick fix.
