I used to play this game so much in high school. Like, for at least an hour a day (when I should have been paying attention in class). Never had an undo button, made it to 16384 once. I have never even considered using a snaking pattern, I always did one side & top (so all rows increased or decreased in the same direction, as opposed to in alternating direction). That is so smart.

I'm not exactly sure what might be causing your problem, but I'm assuming you've tried purging & redownloading KDE Connect?
Another one would be trying to kill whatever process it thinks it running KDE Connect. You could either find it the normal way, or this link might help if you can't easily find the process you need to kill.
I've only ever owned Android, but I was playing over a decade ago. Might just be misremembering, or might predate it's addition.
