I commented out a link in my code to have a link to the graph of a function, and the link went to the url “about:blank#blocked” (edit: instead of the correct URL). After that, my whole screen went black except for the mouse cursor and froze (on chromeOS).
edit 2: crashed again, seems to be random, sometimes the about blank blocked page opens, sometimes it crashes.

edit 3: tried to save system logs of the crash but it crashes before saving the logs. When it crashes it says system restarted unexpectedly, would you like to restore previous apps?

I would guess that the only way to fix this is to just copy paste the link into your address bar. There’s probably something blocking redirects in either your browser or in Vexcode’s site configuration.
