I cant access to my watchlist, the page is in a infinite loop.
Watchlist token: 7288215e7ca7f9b6192fe3d507c85d8878239d43
You have 86 thousand pages in your watchlist. Given T41510 it's not surprising you can't access it. If you want, a sysadmin could clear it for you, but it's unlikely you'll be able to access it any time soon unless you start removing items.
Merging the underlying technical problem into T41510.
A workaround (via a script) for this specific instance of the problem is available in https://phabricator.wikimedia.org/T68212#698926
Watchlist is cleaned now, however, could be better some kind of limit in this list. Thanks
