Pop-launcher failed to start permission denied

Hey, I installed cosmic-epoch with cosmic-launcher and pop-launcher, I do not use Pop OS, but everytime I try to start cosmic-launcher I get following Error: „Error cosmic_launcher::supscription::launcher > pop-launcher failed to start: Permission denied (os error 13)“. Everything within the pop-launcher directory under ~/.local/share/pop-launcher has the permission for all to read, write and execute, I even tried it with crown, but no chance. Maybe here somebody know how I can fix that?
