500: Internal Server Error

[quantum77]

Fedora 35 in a KVM VM, Kodi 19.3-1, plugin v3.0.0 .

ZM is listening on 127.0.0.1:1380 with no auth. Set the plugin URL to http://127.0.0.1:1380, zm path zm, CGI path cgi-bin-zm...

However under API version my only choices are 'Music' or 'Pictures'? Huh?

Auth enabled is Off, but my only choices under Frames per second (max) are 'October', {blank}, 'Pictures', 'Music', 'Settings', {blank}, 'Friday', {blank}, or 'May'.
