My Podlove Webplayer Block in Gutenberg doesnt work

Hello, its me again, unfortunately.
The webplayer Block in Gutenberg i wanted to use on my portfolio site shows these 3 Options: publisher, custom and Post. Aside from me not knowing what exactly these options do, whichever one i click will show the player for just a split second and then go to the error message “missing files” again. The player works in the episode window though.

so essentially if i select an option i get this error message.

Thank you for all the help so far!

I guess in your case with installed Publisher you should be fine using “Publisher” and select the episode you want to embed.
