Youtube seems to have recently added tracking data to URLs obtained through the share button on the mobile application (I'm STILL using Youtube Vanced, so this change was done without a client update)
Found a handy app to sort this problem though, you just click the icon for it instead of the copy URL button in android's share menu, and it can automatically copy it to your clipboard too
