Remoting host process crashes soon after startup (debug and release builds). Probably related to this CL:
https://chromium-review.googlesource.com/c/chromium/src/+/1148471

Backtrace from starting the host process on Linux:

Command-line:
ninja -C out/linux-host remoting_dev_me2me_host
out/linux-host/remoting/chrome-remote-desktop --start -f
