Sending multipart-form file makes the extension host crash

[vabatta]

Hi,

I'm trying to send a file as the following example:

POST http://localhost:8080/api/v1/recordings
Content-Type: multipart/form-data; boundary=WebKitFormBoundary7MA4YWxkTrZu0gW
Transfer-Encoding: chunked

--WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="Sintel.2010.1080p.mkv"
Content-Type: video/x-matroska

< ./Sintel.2010.1080p.mkv
--WebKitFormBoundary7MA4YWxkTrZu0gW--

After hitting send, it processes for a few seconds then the extension host crashes and I get a The test run did not record any output. as well as a popup Extension host terminated unexpectedly 3 times within the last 5 minutes..

I'm on the latest update on MacBook Pro M1.
