After some investigation, I was able to figure out the issue. It has to do with Chrome version 119.
I installed an older version of Chrome 118 and opened the Web Simulator by link and I was able to view the application.
My guess the Web Simulator uses WebSQL and that was recently deprecated in version 119 of Chrome. Only knew this because my Tizen application specifically needs WebSQL to run properly and when my chrome automatically updated one day, the application wasn’t able to run.
EDIT: Not sure if its a complete solution, I sometimes still get the timeout occurred error.
