Can't create access polizy/launch zero trust

Hello

I am trying to re-establish an access policy for my page in order to allow some people to use it for testing. A month or two ago i was able to create an access policy and this all worked fine. Now nothing happens when i click create access policy, there is also no access policy created.

I have also tried to set this up through Zero Trust, however on the 4th step I am shown an error telling me “Name is a required field”, this I assume is from the previous step where I have included a name and wasn’t shown any warning on that page.

Any help with this would be much appreciated, thanks
