Hi again, unfortunately no: option + L does not give any output (cursor stays unaffected).
Please tell us what you have on your list in system settings > keyboard > text input > edit > input sources, and what you have showing in the input menu at the top right of your screen.
German should be option L
German Standard should be option Q
Swiss German should be option G
If other programs have messed this up, you will probably need to change them or make a custom keyboard.
Try using Keyboard Viewer to see which key is doing what on your machine
