the turnstile team is sometimes active in #turnstile-beta but imo you'd need more information, like OS/Browser/etc environment questions, you could try searching the community forums as well for past posts
that looks like a chrome loading iframe issue, and it looks like the screenshot says something along the lines of the widget crashed, you said you tried other browsers like firefox?
edge is just chromium under the hood, I would try a browser with an entirely different rendering engine like Firefox to try to isolate the issue more, sometimes different browsers give better errors as well
in Zero Trust what would the best practice be to allow everyone that has gateaway activated/enabled/enrolled. Do I use a bypass for that and block everything else or is there a better / correct approach to it ?
