I am trying to: Create a new View, but I can only select existing views and not create a new one. Also, I cannot create filters. When I want to create a filter it asks me to select a field, but there are no selection options. See attached images.
From this I gather that you may have the classic editor settings enabled for view.
If the classic view is enabled you can enable the hybrid option by going to Toolset -> Settings and scrolling to Editing Experience. From there I recommend that you select " Show both the legacy and Blocks interface and let me choose which to use for each item I build".
This will allow you to have access to the classic editor as well as the block editor.
