Unable to delete a chanel

Hello,

I created a team for my department and inside this team a couple of channels. As we were experiencing with it to determine the best possible way to use it we created a couple of channels, so far everything went great.

The problem is, that upon deciding that we won't need that many channels that we created, I was not able to delete one of them. (I succeeded with 4-5.) It said that it was deleted but showed up the next day again. I checked it in Sharepoint and its folder was there (although empty), tried to delete it but I got this message: "To delete this folder go to the channel in Microsoft Teams."

In MS Teams the channel shows up until I left click it, then it disappears. If I don't click on it just access its settings and try to delete it, I get the "Something went wrong, try again later" error message.

Could any of you advise?

Thanks in advance!
