I'm not sure that having too many programs running would cause that issue, but if your computer gets stuck like this again try holding down the power button for 10 seconds to force it to shut down completely, then try to turn it back on.

As I mentioned in our chat earlier, with BIAB, you shouldn't have many issues with Mojave, but I personally prefer High Sierra. Do not upgrade to Catalina or higher as BIAB 2018 and earlier will not work.
