Huawei p30 lite does not take screenshots because I supposedly run out of memory?

If I want to take a screenshot (no matter which way), my mobile phone shows a notification where it says that no screenshot can be taken because I have no storage space.

But I have enough on the mobile phone as well as on the memory card…

Over 100GB on the phone

And on the memory card also over 20GB

… Thank you in advance

Can you take normal pictures?

Yes everything runs normally

Have you ever had the optimizer clean the cell phone and have you restarted it?

Check it out with the app

Funny. Then unfortunately I can't help you. Maybe try to restart the phone.
