Is this problem serious? What could be the cause? Thanks.

A number of things could have caused it. Brick veneer is usually nonstructural, however, it could be dangerous and or a symptom of a much bigger issue. Contact an inspector to look at it.
Is what a problem? Could what be the cause?
I can’t tell crap from that pic. What the heck are we looking at and what are you concerned about.
All I see is what may be a ‘brick ledge’!
Google it!!
I mean that a portion of the brick veneer wall was not completely supported by the brick ledge.
If it’s “sliding” as you say, it’s a big deal and hazardous. What evidence do you have of movement vs that being the original placement? Brick can be cantilevered or corbeled by up to 1/3 of its thickness. Did you measure?
If it’s like that around the perimeter of the home or even consistently on one side of the home or wall I’m pretty confident it was built that way.
