Camera and Microphone wont respond

Hi I am using Jitsi Meet, temporarily using the Jitsi servers instead of mine. I have Embedded the meeting onto my website for my family to join, but when I join, the bottom bar just says ‘Configuring Devices’. It has said this for half an hour, and I know my Mic and Cam are allowed because I have just gone into the site settings. Is this fixable?

EDIT

It is working now, although this happened to someone else who was supposed to join which meant we had to go back to Zoom, which I do not like.
