Can't access to /panel/users anymore

Can’t remember what newbie mistake i did, but now i can’t access the users management screen in the panel anymore (/panel/users). I’ve got the following error :
"The data could not be found ".

Any clue how i can solve this error ?

Can you log in to the Panel once you are logged out?

Yes i can log in and out the panel. no problem on this side.

Which Kirby version are you using?

I’m using the version. I think that the problem occured when i upgraded from 3.7 to 3.8.

Turns out the error occured because of a plugin i was working on.
