i used to use in photoshop a tool which was able to transform a polygon with 4 sides to a rectangle. on ordre toi make perspective disappear.
If it is a photograph, then the Gimp perspective tool in backward mode is just as convenient. Set a grid of lines, adjust the grid to match the out-of-perspective and apply.
This a 40 second demo https://i.imgur.com/jJQqw0Z.mp4 If you search, any number of over-long videos.

Make another U formed rectangle path using guides. Then use the plugin 'Filters / Distorts / Perspective Transform / Perpective Transform :4 points to 4 points'
Picture to transform with the 2 paths :
