App doesn't shut down and can eventually freeze up the computer

After I exit the desktop app v.0.4.4 on Windows, it stays active in the background, showing up in the Task Manager, with “Very high” power usage (but “Low” power usage trend). The process entry adds up every time I re-open the app. Unless I manually perform “End task” on each instance, these multiple Logseq processes often increase usage of RAM/CPU on their own, eventually to a point of almost completely freezing the operating system (when I forget to manually terminate the processes, the freezing is usually gradual that I can intervene before it gets too late).

I often use the inspector when editing the custom CSS. Could that cause the abnormal behavior? Or is it an inherent known issue of the app?
