This only happened after upgrading to 19.04.
Everything works fine if i attach a mouse to my laptop. But without it i cannot scroll through the programs because my touchpad does not have a built-in side scroller.
All was fine with Ubuntu 18.04

This sounds a little like bug 1716232. But mostly the issue here seems to be that your touchpad doesn't support scrolling(?).
Have you tried configuring the various scrolling methods available in:
Settings > Devices > Mouse & Touchpad > ...
?
