Your screenshot shows that you are playing in an outdated Beta version of the game. We only accept bug reports for the latest Beta version, which is currently 1.21.120.22. Please update to the latest Beta version and see if the issue persists. If it persists, please create a new report and include the names of the world templates.
I have the same thing happening only it is on my Apple iPad OS 18.7
Any world made, using a template, will not be created. It is easy to reproduce, since simply trying to create any world, with a template, causes it to default back to the create page (screen).
