Hey I am new to the dark web and I am having trouble understanding some problems with tails.

Whenever I click power off or restart in the tails menu the screen goes gray and shows a bunch of white words. Sometimes the first word says Failed in red but doesn't always seem to be the case. It stays on this screen forever and never properly shuts down by itself (I have left it on this screen for over an hour). I have to hold the power button on my laptop until it shuts down. I have also tried pulling the usb and the same thing happens with the gray screen.

I figure that holding the power button does not allow tails to erase all of its memory before shutting down so there might be security implications with doing it that way but I am not completely sure.
