Figure axes not appearing when using tex syntax

Hello all, I recently got a new macbook and it seems that in the figure window I'm not able to display tex labels. For example, when I run this code:

x=1:100; 
y=x/10^20;
plot(x,y); 
xlabel('x_i'); 
ylabel('\theta');

This is the plot I would expect to get. However, what I actually get is

As you can see, no text formatting like I requested. I haven't had this issue on any other OS, so I'm wondering if this is Mac specific?

Note that other labels display perfectly. For example,

xlabel('x')
ylabel('y')

Displays without issues

x = 1:100; 
y = x./10.^20;
plot(x,y)
xlabel('x_i')
ylabel('\theta')

Out of curiosity, what happens if you write

tiledlayout(2,2)
nexttile
xlabel('x_1','interpreter','tex')
ylabel('\theta','interpreter','tex')
text(0.5,0.5,'\theta x_1','interpreter','tex')
nexttile
xlabel('$x_{1}$','interpreter','latex')
ylabel('$\theta$','interpreter','latex')
text(0.5,0.5,['$\theta$ ' ' $x_{1}$'],'interpreter','latex')

text
