User cannot delete or change maturity state of files

Hello,

I am facing to a problem, which is a bit strange as i have done these steps lots of times.

I have an ASM with 2 parts on a collaborative space, and i have inserted it in a bookmark.

After that, i am trying to set this asm from state "in work" to "frozen", but i cannot, as the error message says that i don't have the privileges. I am already the leader and owner of this space, and also i have tried it as Default Administrator. I have also tried to delete this asm but it keeps saying that i don't have the right credentials. I am already administrator at our tenant and also on every space we have.

I tried this workflow yesterday, and i didn't have any problem. I also tried it on different files and seems to be working.

Today also, tried to create bookmark with any credentials, but always showing up the message:

Is there any suggestion of anyone?

Thank you team😊
