Appimage crashes on startup

[StuntsPT]

I have just downloaded the appimage from here.
However, when trying to run it I get this error:

./cutepeaks-x86_64.AppImage                                                  0
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: xcb.

Reinstalling the application may fix this problem.
[1]    14120 abort (core dumped)  ./cutepeaks-x86_64.AppImage

Arch Linux fully up to date as of today.
Running on Wayland, but XWayland is available.
Installed version of Qt5:
Qt5-base 5.12.2-1

If I compile from source, everything works as expected.
