Kernel panic on Mac OS Catalina

[xowor]

Uploading sketches from the Arduino web Editor sometimes causes a kernel panics on my Mac. OS is Mac OS 10.15 (Catalina), and agent version is 1.1.98-fcf6b6d.

Relevant (hopefully) part of the panic report by Mac Os:

@xowor if you get a chance to do a test with the release 1.2.0 please share your results and reopen the issue.
