Huawei smartphone gallery can't be opened?

I can no longer open my gallery on my Mate 20 pro and I still have a lot of storage space. What could be the reason and what can I do to fix the problem? : /

Did you delete the cache or forcibly stop the app?

Yes, tried both.

Can you connect the phone to the laptop and transfer the pictures? Then I would do that and then reset the cell phone.
