Crack through the basement wall of the villa

(Please let me know if I'm posting in the wrong forum, thanks)

Bought a house last autumn. Hultfredshus built in 1976.
Already during the inspection, a crack was visible on the foundation wall/cellar wall (concrete). The inspector wrote the following (among a lot of other information of course):

[TABLE="width: 100%"]

[TD]Foundation Basement[/TD]

[TR]
[TD="align: left"] There are cracks in the foundation wall/cellar wall. If you want to check whether the cracks from any movement in the building are ongoing, it requires drilling dowels into the building's base or near the cracks, and precision leveling of the dowels should be performed against a fixed height. Such a measurement should be done regularly for at least a year to assess any movements or settlements. [/TD]

[TD="align: left"] No signs of water intrusion or damp spots on accessible surfaces at the time of inspection. Nothing special to note.[/TD]
[/TR]
[/TABLE]

I believe, unfortunately, the crack has increased in length somewhat since the inspection. It should be noted that the previous owners made some changes outside the house wall on the short side about 4 years ago. See the image with the encirclement. They removed the soil there (to reinforce the "flower bed wall" and install the wooden stairs).

Anyway, I intend to do something about this to at least prevent water from seeping in.

Appreciate any knowledge on how I should proceed?



Thanks!
