Roblox font
The Roblox logo is custom lettering, not a font you can install.
Roblox's own announcement (Aug 2022, CEO David Baszucki): the refreshed wordmark uses new custom letterforms, lighter than before.
What the Lettering Looks Like
Heavy geometric sans-serif capitals in black; the first O is a large tilted square with a small square hole, while the second O is an ordinary round letter.
