Rear flap no longer opens from the outside

Good day, dear R class friends, I have the following problem with my R class W251 320 CDI 4 Matic Diesel with 224 hp: and indeed until yesterday my tailgate went too but only with really good taste, and since today it did not open from the outside so with pressing the rear flap handle. So I tried to unlock the tailgate in my emergency and that went away, so my conclusion was that the lock of the tailgate cannot be broken, because otherwise can I hope you can help me with the problem then it’s really exhausting if you don’t get to the trunk from the outside. No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no.
