The platform failed to initialize. Exiting.

[Patrikios]

If I try to run the command

library(chromote)
b <- ChromoteSession$new()
b$view()

the code exists with:

> library(chromote)
> b <- ChromoteSession$new()
Error in `startup()`:
! Chrome debugging port not open after 10 seconds.
Run `rlang::last_trace()` to see where the error occurred.

If I do:

library(chromote)
Sys.unsetenv("HTTP_PROXY")
Sys.unsetenv("http_proxy")
b <- ChromoteSession$new()
b$view()

The error is:
