3 April 2023 Alert: Recent changes to Vaultwarden may cause Vaultwarden to fail to start due to default environmental variables. .env.template has been updated in this repo, however, if you are affected, you must also update .env and comment out all YUBICO_* variables, so that they appear as:

#YUBICO_CLIENT_ID=
#YUBICO_SECRET_KEY=
#YUBICO_SERVER=

Restart with docker-compose, and Vaultwarden should come up as normal. Credit to @AySz88 for reporting this.
