I saw your first post, but I didn't understand anything.
After you wrote your second post I am writing this reply.
How do you upload files to hosting?, the most reliable way is FTP with full write permissions.
After uploading a project to the website via FTP, subsequent updates (file replacements) and attempts to refresh the page using CTRL+F5 or on a new device result in a black screen without proper loading. It is necessary to rename the folder on FTP, creating a new link, to successfully load the webpage.
