DotTrace detaches after sent start command

Question

I am attempting to use the DotTrace command line tool self profile my application (I would use the NuGet, but it has a blocking bug.)

It starts up just fine. I create the dotTrace process and attach it to my application. I then use standard in to send it the "##dotTrace["start"] command. I have done this in a demo app and my real app. In the demo app, it starts profiling after that command is sent.

In my real app it responds with "##dotTrace["disconnected"... as if I had sent a ##dotTrace["disconnect"] command.

It does not give any indication why it detached, just does it as if I had requested it.

How can I figure out why detach was called?

Looks like the profiler crashed just after start. Could you please add --core-log-mask=55 to the dotTrace command line? It will generate a log file in %temp%\JetLogs. Please, share the folder JetLogs after that.
