The problem will be in your settings somewhere. Without actually seeing what you are doing, difficult to provide solutions.
You might have to reset your tool options to get back to basic settings.
If it was my installation, first thing to track down a problem, is unplug the tablet. It is just an added distraction.
Then it could be anything.
As an example, fuzzy select with a default threshold 15 and it selects a portion as expected.

With a high threshold, it looks like it does not work.
In reality, the whole image is selected but superficially it looks like nothing happened.

That is the sort of setting you will have to look for, not only for using a mouse but also your tablet.
