The page dont works

when i try to start a new project, it tells me that i can’t access the files on the pc, but i have everything set with the permissions. i´m using chrome, y have dishabilited all secure measures, but when i try to start a project, it does not work and creates me a project with only the “minecraft” folder and “soundevent”. it does not work when i try to install it to my pc, and when i try to go to the “blocks” section, it only leaves me in a blank page.
