Extras/other people in the background are acceptable to meet the criteria but ideally with no human/entity on the screen at all that isn’t played by the same actor.
Movies like ‘Men’, ‘Moon’ or ‘The Nutty Professor’ don’t meet this criteria for example, due to the exceptions of characters played by other actors.
And it has to be somewhat mainstream and not a low budget student film or something.
Edit: I also meant that they play multiple characters…
Not a film, but there’s a DC animated short where Mark Hamill voices every character.

I wouldn’t count anything that isn’t at least arguably as long as a movie. Wallace & Gromit: A Grand Day Out and the SpongeBob episode “Gary Takes a Bath” otherwise would count as well. There’s probably an otherwise qualifiable clone-focused episode of The Clone Wars, too.
The ones that come to mind all have other actors in the beginning or end, or voices from other actors. Locke, Buried, 127 Hours, Cast Away, Gravity…
IMDB tells me All is Lost lists only Robert Redford, but I haven’t seen it to be sure.
Wikipedia says All is Lost has only 1 character, but I did find a SPOILER scene that shows Redford by someone else’s arm for only a couple of seconds. I’d figure this is the only scene with anyone else onscreen.

Bo Burnham: Inside?
You’re right technically… but i should have said “fictional story” and “plays multiple characters”

Buried, Ryan Reynolds is the only one on screen (not playing multiple characters, just one), though there are voiced characters from other actors on the phone.
I always forget about that movie, but it’s really good.
Being john malcovich?
Not quite… but there were a lot of john’s…
Malkovich, Malkovich? MALKOVICH!
Any classic Looney Tunes movie.
Kind Hearts and Coronets (1949) has to get an honorable mention, in which Alec Guinness plays eight significant characters.
Wasn’t Tom Hanks the only actor in Castaway? Unless you count the volleyball.
Not for the entire movie. There are scenes before and after his time on the island with other people.
It is the same reason why Moon wouldn’t work. Sam Rockwell is playing the main characters, but you have a significant voice acting role and several very minor characters.
