Migration to 11 won't start : "libc6-dev : Breaks: libgcc-8-dev"

I’m affected too:

Les paquets suivants contiennent des dépendances non satisfaites :
Info : + libc6-dev : Casse: libgcc-8-dev (< 8.4.0-2~) mais 8.3.0-6+rpi1 devra être installé

Do you think the system is safe now that the migration aborted after marking some yunohost packages on hold and ?
