NullReferenceException: Object reference not set to an instance of an object and Unable to open game
This is on a fresh install of MTG Arena on my windows laptop (I previously had wiped Arena off my laptop with Revo Uninstaller), Downloaded all of the recent patches as of today (2025-06-29) and thankfully was able to keep arena open for the 20 minutes to claim a quest in discord, but I am still stuck at this screen after the full 20 minutes have elapsed (see attachment).
I attempted to log into Arena on both my iPad and iPhone (again, fresh installs on both platforms, never downloaded it there) to try and claim the sleeves from the quest before it expired, but I encountered the same screen.
I attached the Log file generated from my laptop, the only thing of note that I see is a NullReferenceException: Object reference not set to an instance of an object occuring after the WaitingForMatch start, but notably this was the only logging that happen until I forced closed the application from task manager at 12:35
Since this issue is occuring across multiple platforms and on fresh installs, I submitted this as an account issue, as it appears to persist no matter what platform or wifi network I play on
I am unable to even open the game beyond that initial screenshot, which unfortunately means I am unable to enable detailed logs, so the log posted is the best I can get. I have tried a few claimed work arounds from reddit and this page to clear cache, I've uninstalled with Revo numerous times, but nothing fixes this bug.
