@moomiji Thank you for reporting this issue. We are working through issues and will look into this one as soon as possible.

Is there any way you could attach the core dump? Zip it up to make it smaller?

[moomiji]

Hi @mikem8361 ,

I zipped a core dump file which attached by dotnet-dump collect --type Mini.

This should be fixed now. It may be a month or so before our next tools release that includes this fix.
