Has someone faced a problem which doesn't allow you to play vs the computer because it says "Error, invalid FEN" when you try to play vs computer?

When you play the computer from a certain position, you can enter a FEN.

For example the starting position FEN is: rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1

Maybe your current selection is to start with a FEN. Try to start a normal game instead. Hope it helps.

If you find FEN usage difficult, then you can go into the Lichess menus -> Tools -> Board Editor
Set up your preferred position and then click on "Continue from here" and choose to play against the computer.

Fen is some random posititional apex Type CX code, based on a hexadomic systemal arrangement of the pieces.
