Take a day or two off and do nothing. Or do something but no coding. Binge watch some shows, read a book, exercise, go to the movies, anything but work. Better yet, chain those two days off with a weekend. See if when you come back you have some focus. This will probably get down voted but, you could also try re-arranging your workspace to whatever extent you are able to do that. Get a plant for your desk, change where you sit, rearrange furniture if you work from home. Clean while you're at it. Maybe something is off or just needs to be refreshed, especially if you've worked remote for the last year and half.
