Text appear in black squares

[celeste]

Hi, I just downloaded steam and Celeste, but there is a problem with fonts.
I ran Celeste, but the alphabets of the main page only appear in squares.

What I have tried:
- changing interface languages
- checking game file integrity test
- deleting steam, Celeste and downloading again

But none of these worked. How can I figure this out? I need help....

Have you tried restarting Steam/your computer?
Have you tried updating/reinstalling your drivers?
Have you tried switching to the OpenGL beta branch? (Library -> Right-click on game -> Properties -> Betas)
