It looks open in your screenshot but the window is too small, try pressing F11 to fullscreen the window.

Didn't make any difference at all, Firefox still frozen and wont open at all. Tried uninstalling and downloading again still didn't make any difference.

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

See "Visual Studio 2015, 2017, 2019, and 2022":

Does it still happen with Developer Edition?
