Same here. I have no Solution, just a workaround and I hope they fix it soon. You can disable the CORS safetycheck in chrome. Run chrome.exe with --disable-web-security and set the user-data Directory temporary to another location, with the following parameter and the folder you want --user-data-dir=c:/anyfolderName/`

It seems to be a bug on googleapis or maybe youtube.v3.apis had a policy change and started to block some clients.
