Card no longer opens

[Magnet Formula - Area Web 1]

Hi everyone, I'm having an issue with a tab that I've never encountered before. Suddenly, it's impossible to open. If I click on it, the attached screen appears, saying "Tab not found." I also noticed something strange in the list, as the tags that were activated within the tab also seem to have disappeared.

@Magnet Formula - Area Web 1 is the card a mirror card that was archived, or something you don't have access to? I'm wondering if what's happening is you're previewing a card in the board, but when you click on it, it realizes you don't have access to it. Are you using any power-ups? 

I'm also clicking the button to request assistance from support here.

Thank you @Brittany Joiner !

Hi @Magnet Formula - Area Web 1 , welcome to the Atlassian Community and thanks for your post.

Have you already tried these things - https://community.atlassian.com/forums/Trello-articles/Can-t-find-your-Trello-cards-Try-these-troubleshooting-tips/ba-p/2947608 ?

Is it possible the card has been moved from another board and lost these attributes in the process? https://support.atlassian.com/trello/docs/moving-cards-or-lists/ 

Please let us know if you are still having this issue so we can find other troubleshooting support.

Best wishes

Hi Valerie, thanks for your reply. The first article you linked refers to a tab that's not even visible in the list, while mine is visible with all the others, but when I try to open it, the error message "Tab not found" appears.
I also tried in April from the context menu, but the result is the same. I added a label, which I see in the closed tab, and I moved the tab from one list to another, but these actions didn't solve the problem either.
It's a tab I've used for a long time without any problems, and once I finished working, I moved it to the current board—an operation I do constantly with many other tabs, without ever encountering this problem.

@Brittany Joiner , can you help at all? or tag / recommend another Trello expert?

Thanks
