Hi,

Thank you for submitting this report. Unfortunately I can't reproduce the issue without the application used.
It can be helpful if you can find a regression range, so the source of the problem can be located: https://mozilla.github.io/mozregression/.

[BugBot [:suhaib / :marco/ :calixte]]

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Comment 5

[Lars T Hansen [:lth]]

That looks like an assertion raised by compiled code (ie not by the engine) so it could be that the code has detected that we're not supporting some wasm or html or js feature.

Comment 6

[Benjamin Bouvier [:bbouvier] (inactive)]

jjjudas, is there a deployed version of the app somewhere? (Installing Blazor, learning how to use it and building the app ourselves wouldn't scale for us.)

If we had a readily available test case, we could try a few different things, like establish a regression window, test it in different browsers, see if using a specific compiler works, see if disabling some optimizations works, etc. In the meanwhile, there's not much we can do (so setting priority to P5).

Comment 7

[BugBot [:suhaib / :marco/ :calixte]]

Bugbug thinks this bug is a regression, but please revert this change in case of error.

Comment 8

[Ryan Hunt [:rhunt] (on leave until early May)]

Closing this as it's an issue with user code (not the VM) and we don't have any actionable information. Feel free to reopen if there is new information.
