Hello,
today I did try to modify a .bib file with a text editor, because I wanted to add static Groups to my file. I worked with a backup file, and did miss the correct pattern. My problem appeared afterwards. JabRef won’t open any .bib file anymore. Even those files I have been using without any problems.
What I already tried: Reset my preferences & restart the computer.
Jabref always starts normal - but without any files open. When I try to open a bib file, the following exception windows is raised:
java.lang.ClassCastException: class javafx.scene.control.Tab cannot be cast to class org.jabref.gui.LibraryTab (javafx.scene.control.Tab is in module org.jabref.merged.module@5.2.376 of loader 'app'; org.jabref.gui.LibraryTab is in module org.jabref@5.2.376 of loader 'app')
