Skype falhando na instalação do Ubuntu pronto para uso

Fiz uma instalação nova do mais recente Ubuntu 24.04.1 LTS em um laptop HP de segunda mão. Uma das primeiras coisas que instalei foi o Skype usando o Ubuntu Software Center. Executá-lo usando o inicializador faz com que ele seja iniciado, e ele aceita um nome de usuário e senha com validação com os servidores do Skype. Depois que você digita a senha, a tela fica em branco e permanece assim por mais de uma hora.

Executar o skype na linha de comando resulta no mesmo comportamento, com a saída abaixo. Todas as linhas, exceto a última, foram produzidas antes da entrada do nome de usuário/senha.

O que posso fazer para corrigir esse problema?

username@username-HP:~$ skype
+ [ -f /home/username/snap/skype/common/.config/skypeforlinux/settings.json ]
+ export SKYPE_LOGS=/home/username/snap/skype/361/logs
+ [ ! -d /home/username/snap/skype/361/logs ]
+ exec /snap/skype/361/usr/share/skypeforlinux/skypeforlinux
