"App not starting" issue

Imagine having worse customer service than Ubisoft. To relegate the topic to forums instead of attempting to deal with the problems individually. Phone companies handle millions of clients on a personable basis every day, but a "Triple A" Publisher making billions of dollars a year can't even do the basics.

Hi Tygronn,

Sorry to hear you’re running into this issue, and that live support wasn’t able to help.

You mentioned that you’ve already gone through all the usual steps for basic troubleshooting and that this seems like a larger issue. If it were something widespread—like an "App not starting" issue—we’d likely be seeing many more reports, but that doesn’t seem to be the case right now.

To help narrow things down, could you list exactly which troubleshooting steps you’ve already taken? Let’s make sure we’re on the same page before diving deeper.

Not to come off as rude but you need not look further than the front page to see plenty of topics on this same issue and googling shows it's not a recent bug but something that seems to just trip over time or something. I don't see how that doesn't count as "many more reports" also accounting for the fact that a majority of people are going to look here, see it says the same unhelpful copy paste troubleshooting and not waste their time making their own thread. Tbh I mostly came here to vent my frustrations, but if you're willing to play ball let's play. 

As for what I've done I've done about every combination of uninstall, download new installer, run that. Or repair this time. Or uninstall, reboot, reinstall. Or repair and reboot. Including using revo uninstaller which tbh I'd like to never have to install again as I don't really trust it and despite the negativity Microsoft gets these days the built in tools do the job just fine without issues. Revo didn't fix the issue anyway. And yes I've made sure Windows is up to date. I'm on Windows 10 Pro for what that's worth, I'm not switching to 11.

Pretty much the only thing I haven't done is reinstall Windows itself and that's not an acceptable answer. 

Event viewer shows that the app has crashed, in the report it mentions a dll file "ntdll.dll" but looking up related issues to that looks like I'll only make things worse by trying some solutions people have said around that.
