I updated my WP installation to latest along with all the plugins. However I cannot update ACF.
First I need to change theme or the database upgrade for ACF hangs into infinity. If I change to classic theme eg Twentynineteen database upgrade for ACF goes along fast. But then all the fields are gone, the plugin button is reverted to the old custom fields (just as if I disabled the plugin). I tired getting some debug logs in here but I didn’t find any.
