Could Not Reproduce MTGO keeps crashing with Shiny.App.Dispatcher_UnhandledException

[rnelson]

I fired up MTGO for the first time in 8 months to play a Magic 30 cube draft, and MTGO crashed 4-5 times during the first pack with Shiny.App.Dispatcher_UnhandledException (see below for the longer exception log, reduced to get under the 10K character limit). I was able to finish the draft and play two games, but during the third game, I got the same error again and timed out because I couldn't get back in to MTGO without it crashing.

I filed for compensation and got my draft token back, started another draft, and received the same error during the third pack. Now, whenever I try to edit my deck, MTGO crashes with the same error, so I can't play any matches.

I uninstalled and reinstalled MTGO, but that didn't fix the problem. Please help.

Don't know if it will help your particular problem, but it shouldn't hurt. Someone posted elsewhere his workaround for the re-installation bug:

"This fixed the issue for me: Disabling Microsoft Compatibility Appraiser scheduled task under Task Scheduler Library > Microsoft > Windows > Application Experience seemed to also work as long as the task stays disabled."

Thanks for the suggestion, but that didn't fix the problem.

This was the initial error I was getting:

Now, I don't even get an error message--it just crashes after I attempt to edit my draft deck:

I followed the "Uninstall Magic Online" and "Clear the ClickOnce Cache" steps here but still get the same error: https://help.mtgo.com/hc/en-us/arti...tall-or-perform-a-clean-installation-of-MTGO-

I also deleted all of the MTGO folders under "%LocalAppData%\Apps\2.0" (I had other applications there, so I didn't want to delete the entire folder), and no change--still the same error.

I opened up a MTGO prize pack, and MTGO crashed with the same error. Now, whenever I go to my collection, I get the same error; also, the two cards I opened in the prize pack are blank in my collection:

Our Dev team had a look at this and suggested the procedures mentioned in this article (use regedit.exe and look for invalid/missing paths) as a possible solution.

Thanks for the suggestion. Are there any specific keys I should be looking for in regedit (or is there a way to display just the invalid/missing paths)?

I have no additional info beyond what is in the article

You might want to try Revo Uninstaller. It does an excellent job of removing extraneous Registry entries relating to whatever app you're uninstalling.

@rnelson Did you ever find a solution to this? I'm getting this crash on startup 100% of the time and can't find a solution after doing all the standard listed troubleshooting

Thanks, I tried uninstalling with Revo Uninstaller the first time, but no luck.

No, I never found a solution. I filed a ticket with Daybreak, and they were very helpful, but none of their suggestions worked. They ended up resetting my password and logging in on their end, which worked for them, which means it's a problem with my computer and not my account. Their last suggestion was to do a full clean install of Windows, which I do not want to do.
