VirtualBox not starting due to Qt incompatibility

[jmac]

If I try to run VirtualBox I get the following:

Qt FATAL: Cannot mix incompatible Qt library (5.15.6) with this library (5.15.7)
Aborted (core dumped)

I don’t know when this started as I haven’t run it in a while. (My system is up to date, fwiw.)

This has been gone over many, many times:

• Check the mirror you use is up to date:

sudo pacman-mirrors -f 5 && sudo pacman -Syyu 

• If you use qt5-styleplugins (AUR), rebuild or remove it:

pamac build qt5-styleplugins

Updating the mirrors fixed it. Thank you.
