plot doesn't work

The function plot doesn't work anymore, i tried to use the commands 'close all' and figure() before running my code but it doesn't show anything. For example,

clc, clear, close all

x=[1,2,3,4];

y=[2,3,2,1];

figure()

plot(x,y,'b-')

the plot comes out without a figure and it's gray.

Does someone know how to fix this?

Thanks in advance

Works fine for me in r2022a and in MATLAB online:

clc, clear, close all
x=[1,2,3,4];
y=[2,3,2,1];
figure()
plot(x,y,'b-')

What appearance are you looking for exactly?

You don't have an m-file called plot.m do you? What does this show:

which -all plot

I solved it by reinstalling matlab, i don't why it didn't work, i don't have any file named plot.m, but thanks anyway
