Old APP_KEY: base64:2HRMaEZZjSCUwwkpAs87wnWquiYs83Wnw2ef4cyy4iY=

Document BOTH keys! In case something goes wrong set the new key in .env and use the old key as an argument to this command

This command could cause irreversible loss of data and will invalidate all browser sessions. Make sure you have backups.

 I have backups and want to continue (yes/no) [no]:

If it is a new install and you don’t really care then just delete ‘validation.encryption.test’ from the config table…

perhaps
./lnms config:clear validation.encryption.test
or go into the database, find the config table, and delete the row where the name is
validation.encryption.test

Can you tell me which path the ‘validation.encryption.test’ is on?
