Might try a low stakes, low stress first person puzzle or platformer. Was playing Faraway: Puzzle Escape a few weeks ago. It's mouse look, WASD movement, no jumping, and no deaths or timers. Gentle gameplay, relaxing music, the puzzles are difficult enough to be interesting, but easy enough that I played the whole thing in one sitting between lunch and dinner....and I didn't feel tempted to throw anything.
I got Faraway 1&2 off Amazon prime games, think they might still be available.
My thinking is that it'll get you used to how to move around without being aggravating, and without adding too much complexity to the movement.
Or play Portal.
