"Auto start Seafile after login"-option does not get saved


I recently installed Seafile on my MacBook (macOS Catalina Version 10.15.4) and noticed, that Seafile did not start automatically on login. I checked the checkbox at Menubar -> Seafile -> Setting -> Auto start Seafile after login, but had to notice that Seafile still didn’t start after a restart of my MacBook. A second look into the settings showed that the checkbox “Auto start Seafile after login”, was unchecked again.
How can I approach this problem? Maybe Seafile doesn’t have enough rights to write it’s own config file or something?

Thank you for your help!
