Insomnia becomes unusable when a request contains highly nested JSON

[loop-evgeny]

Expected Behavior

Insomnia is usable for any input text.

Actual Behavior

With highly nested JSON as input Insomnia uses 100% CPU for a while, then the entire window goes black and nothing can be done except to close it:

Even after restarting Insomnia it's unusable, because it automatically opens the last request and goes back to the same state!

Reproduction Steps

Create a new request, set input type to JSON and paste the contents of very-nested.json.txt into the textbox.

Is there an existing issue for this?

• I have searched the issue tracker for this problem.

Additional Information

I worked around it by editing "%AppData%\Roaming\Insomnia\insomnia.Request.db" in a text editor to delete the request.
