As far as I'm aware, it's working fine for everyone else - it sounds like only you are having trouble. Perhaps you have a browser extension installed that is interfering with Construct and breaking it? Try disabling any browser extensions you have one-by-one, or try a different browser.
If you're using a third-party Construct addon, it may be that the third-party addon is broken and is causing the problems. In that case you'd need to contact the addon developer for help.
