I think some people sabotage relationships for the same reason they throw video games. They have fears/suspicions that it's going to not work out, and rather than be a victim they want to have some control over the outcome. A loss or failed relationship doesn't hurt as bad if they caused it to end the way it did.
However in your case, it sounds more like a fear of something different. It's a lot easier to keep things like they are, when a relationship gets too serious or life impacting it can be easy to be scared of the change, and instead subconsciously decide you want to keep things like they are.
Recently ran into an issue with Endeavour OS where the built in printer program would give errors when trying to add my network ecotank printer.
Tried using cups terminal and it worked the first time, and is still working weeks later.
So some of the GUI printer apps that distros ship with have issues apparently, but I don't know the extent of it.
