What was the last working version - 119 or 120.0.2210.61? Does it repro on different devices with different windows versions or only that particular one? Could you share the dump file?

@vbryh-msft Not sure about 119 or 120.0.2210.61. We tested our app earlier when we published to the store was Runtime: 114.0.1823.58. I don't see any dump file in that location.

I think I have found crash reports which may be the same issue and folks are looking into it. Could you please disable the feature --disable-features=RendererAppContainer - it should fix the crash.

@vbryh-msft that means i have to release a new version of the UWP app to the store adding the command line to disable the feature ? What is the impact of disabling always with the command line --disable-features=RendererAppContainer ?

Hi, we deployed configuration which should fix the issue - it can take few restarts of the app and some time to have applied.
Let us know if you are still able to repro it after few days.
Please consider setting-up some testing on our prerelease channels and keep reporting the issues. Thanks!

This is fixed in 120.0.2210.121+
