Help me find something please

I want to reread something but I cannot remember the name at all. I only vaguely remember the story itself.

It's about a woman who developed an immersive game, but when she played it she got stuck inside it. Because the setting of the game was set in older times where women weren't allowed to do a lot, she disguised herself as a guy, went to I think was the duke and said she was an inventor or something.

Ofc the woman and duke fall in love.

Does anyone know which story I might be talking about? I really really wanna reread it again.
