unserialize(): Error at offset 429 of 494 bytes

I am putting my Laravel application into production, and I get this error message: unserialize(): Error at offset 429 of 494 bytes

I tried :

php artisan key:generate
php artisan cache:clear

No idea what could be this error... Here the error : https://hagnere.bimcode.fr/

Did you ever find a solution for this problem? I'm having the exact same error with exactly the same offset and same number of bytes.
