PROS vscode extension not installing

I have installed VScode on windows, but the PROS extension is not installing. I clicked install on pros, and it said “Preparing to install PROS” and has been stuck for 30 minutes. Did I do something wrong?
edit: on the extension page, the images did not load.
edit: I installed the vex robotics extension, it worked fine, but it can’t program the v4 brain.
