Closing the InputFile (with file or cancel) dialog in Firefox crashes Aspire

[hyyylight]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I made a new Blazor Web App with Aspire Orchestration 13.1 using the project template and Include sample pages
I open the counter the sample page and add "" to the page.
I start the application using the AppHost and open it in the current Firefox version and go to the Counter Page. I click on Browse.
The Dialog opens, then I click on Cancel and the App Host crashes.

When I start the Blazor App directly without AppHost everything works fine.

Expected Behavior

The App Host doesn't crash and everything should work as expected.

Steps To Reproduce

I uploaded here a project that I did exactly as described in the section above:
https://github.com/hyyylight/AspireInputFileBugSample

Exceptions (if any)

I don't get any exceptions I tried some methods to catch unhandled exceptions without success.

@hyyylight I'm unable to reproduce this locally using the sample repo you shared. I tried Edge and Firefox, tried launching from the CLI with aspire run and from VS2025 with F5 (debug). It worked fine in each case. Other users have reported this issue but we've never been able to reproduce it, and without an exception message or logs to assist with diagnosis it's difficult for us to assist. Could you try it on another machine to see if it repros there?

Also, out of curiously, can you share whether you have Docker Desktop with WSL installed and running?
