The bounty manager account you are referring to was also active a few days ago. when you see he is still active in completing the spreadsheet which I see is not final yet. that means everything is not finished yet.
While waiting, you can actually go to the project's official Telegram account. look for the admin and ask whether the funds for the bounty campaign have been given to the bounty manager. because there are those who have provided bounty allocations from the start, but there are also project teams who send bounty payments themselves and wait for the final spreadsheet from the bounty manager.
