Solved KB5032288 keeps corrupting battle.net app

MS weren't able to help me, I hope someone here can.

This update for some unknown reason keeps corrupting my battle.net app to the point it refuses to load properly. I went to MS online help after uninstalling and reinstalling the battle.net app failed to make one iota of difference to my then unplayable game. First my system was rolled back, which worked right up until the update came in again.

I returned to MS online help, this time they uninstalled KB5032288, and this time the battle.net app loaded, and then when I launched the game, I could hear the main screens sound effects, but my screen was black. They restarted the app, but the original failure to load the app returned. I was told the problem would be looked into and they would get back to me when they had an answer, in the meantime to roll my system back again, reinstall battle.net and they turned off the updates.

That was almost 2 weeks ago now, I don't want to turn the updates back for fear of again getting an unplayable game again. Oh and I am still waiting for MS to get back to me.

Also because my system was rolled back twice, the screenshots and recordings I had of the issue I no longer have.

Now that I have just typed that out I realise it's probably going to be impossible for a "fix" to even begin without the screenshots of the problem

KB5032288 was a preview update for yesterday's normal update.​

Try installing the official update. KB5033375 Windows 11 Cumulative Update Build 22621.2861 (22H2) and 22631.2861 (23H2)

You can try this:
Make sure you have no corrupt system files that is causing this problem. Open a command prompt as administrator and type sfc /scannow
Pay attention to the scan results to see if SFC found anything it could not repair. If it found corruption it could not fix followup with this command (note the spaces)
dism /online /cleanup-image /restorehealth
Restart computer
(Note-you can follow up with another sfc /scannow command to make sure that dism repaired the files)

Also keep in mind, as windows changes, it is the responsibility of the app developer to keep their app updated to remain compatible with the changes Microsoft makes in windows. If it works before the update, but not after, I would think you have one of 2 choices. 1) stop windows from updating until the developer fixes his app or 2) stop playing the game and keep windows updated.

I waited until the Cumulative update came out, everything is working as it should
