HL2OE having launch problems

okay i know there are simular threads here about this but none of the answers help, so…

well, you probably wonder: what problems are those you talk about? well, it’s a launch error that does not let me play the game, but i can look at this man with a head that challenges an eggplant in the valve intro video over 10000 times trying to fix this, if i want to.
please help me. image

Does the solution here work for you?

no, do you have another solution?
