To be honest, the issue rose before I installed the last Windows Updates. I only installed git via winget yesterday. This is the only new thing that changed on my system between the time it worked and today when MS store tried to update apps and failed. I doubt the problem is due to a Windows Update. If it works after reverting a Windows Update, it could be because the process itself did something generic that helped. Since the error is :
Sorry about that!Something went wrong. We're aware of the issue and working to fix it. Tryrefreshing or come back later.Code: Ox80073CF9
I suggest to wait one week and not trying some fixes that could do more harm than good.
