Recent issues with the HTML5 exercises

Greetings everyone.
I’ve recently been having issues with the HTML5 exercises in the Certified Full Stack Development program.
My workshops and labs haven’t loaded since April 21st.
They won’t even load the exercises I’ve already successfully completed.
I have Chrome 109 on Windows 7 32-bit.
They also won’t load on my Windows 8 64-bit laptop.
I know my operating system and browser are somewhat outdated.
Any suggestions?
Thanks.

you can try the last supported version of firefox
