When I start up my desktop PC, I see GRUB. It disappears for a moment, but then reappears for about two seconds. The computer then starts up normally. How can I prevent it from appearing a second time? Thanks in advance!
In case you mean the company logo of your computer being displayed twice: That’s totally normal for grub.

Did the second grub appear after you run the recommended install-grub after one of the more recent updates? If so, most likely you installed it twice.
What’s the output of:
inxi -zv8

This shouldn’t matter.
This. If not, OP has to explain what does he mean with “grub appears twice”. The menu? Some logo?
Another normal possibility is that itdetects the video or loads module and switches the resolution which will blank the screen for a moment.

By appearing twice, I mean the whole GRUB menu.
Are you able to post a screenshot or photo of each “Grub menu” that you see?

I see something similar, but the second time it seems to be a screenshot of the grub menu. I can’t interact with it using the keyboard. I suspect it is something to do with the lack of a background image setting or logo or something, but I just ignore it.
Can you interact with grub when it appears the second time (e.g. with cursor keys)?

I haven’t experienced this yet myself, but it could just be an echo of the framebuffer while the video mode switches.

It does somehow, I have the same issue. To reinstall grub I used to run sudo grub-install /dev/sdX. Since running install-grub I have the 2 grub menus the OP describes plus another one at shutdown.
For me that would most likely be fixed by running the old command again, never tried, though, since it never bothered me much.
Please note that there are significant differences between the OP’s single gpt drive uefi system and my msdos drive bios system with a second gpt drive for data.
Yes, that was the answer I found for “grub menu at shutdown”, most likely the reason for the second one at boot too.

This happens during the startup messages on my systems as I removed quiet and splash from /etc/default/grub — I prefer to see the messages. I think I get a brief flash of the initial ones on shutdown; will have to look closely next time. (I only typically shut down or reboot following a bundled update).
Maybe @Skoebidoe you could try that, if you don’t mind the messages scrolling up. I’d be interested to see what happens then. Those are in the GRUB_CMDLINE.

Mod note:-
Thanks for the requested images. They have served their purpose and have now been removed.
If the second one is after the nuc+manjaro logos and moving dots a.k.a. Plymouth, it is just a framebuffer artefact.
Actually even before it is very probably this.
Disabling Plymouth partially as descreibed above (removing splash and quiet from the boot line) might or might not help. But i am curious if this is yet another Plymouth quirk (that thing should be banned by law 
)

no, i can not interact with GRUB the second time
In that case, as mentioned by others above, it is probably just a framebuffer artefact. In which case it is not harmful.

Thank you for the screenshots; they can now be removed.
The second “menu” is at a higher resolution than the first, which is likely an artefact of the console resolution changing, much as @Teo and @Aragorn have described (above).
This might be annoying to see but otherwise should be harmless.
However, if you find it too visually disturbing, you could try disabling Compatibility Support Mode (CSM) in your BIOS (if enabled), which may help to some degree (but, no guarantees).
Regards.
