Apple Pencil disconnected line

I got this weird, disconnected line(circled in the image below) when writing/drawing using my Apple pencil on my 8th gen iPad. This same problem happened about month ago which mysteriously gone by the time I woke up in the morning. I tried everything that came across my mind: rebooting iPad, disconnected and reconnected the pencil, changing nib and community suggestion like turning of the zoom but none solve the issue. My iPad is also up to date. Need solution a.s.a.p as I am using my iPad for a lot of illustration.
