Hello.
It could also be a problem with the immobilizer system.
I experienced the same thing recently.
They tend to cause problems as people get older.
It's located behind the light switch on the dashboard (in my Passat).
I initially managed to get the car started again by repeatedly tapping

on the area under the light switch.
The spark plug fuse is, incidentally, located on the fire protection wall on the left side in the direction of travel, inside a small plexiglass box.

It's approximately 1/3 the size of a cigarette pack.
bye
Sure, here is the translation of the text from German to English:
'Micha' translates to 'Michael' in English.
