Can't change CharacterMovementSpeed anymore/ how do I get UCharacterMovementComponent as Variable [C++]

The function gets called from an ACharacter derived class.
I tried to put in your GetCharacter Pointer but there was no reference of it.
Thank you for the answer though

EDIT:
I was actually able to test if the variable is cnahgend over the pointer and it worked out, however, the varaible doesn’t seem to be able to be changed in the actual instance/blueprint. does anybody know what there is to watch out for in terms of settings of the blueprint?
Thanks for the help sofar :smiley:
