Hey guys, I have the same issue, which is probably the same as in this 6 month old thread: https://ww.wp.xz.cn/support/topic/this-key-is-invalid-or-has-already-been-used-please-reset-your-password-again-i/
Just updated User Registration & Membership to Version 4.1.3 and WooCommerce to Version 9.7.1 then the problems begun.
If deactivating User Registration & Membership everything works fine.
Thanks,
Mats
