Failed upgrade from 4 to 5

Your software
My Mautic version is: 5.latest
My PHP version is: 8.0.3
My Database type and version is: MySQL

Your problem
My problem is: after upgrading via CLI logs are showing Mautic is down.

These errors are showing in the log:
[2024-05-01T22:38:57.579498+00:00] mautic.CRITICAL: Exception thrown when handling an exception (Mautic\CoreBundle\Exception\BadConfigurationException: Mauve is missing a required config file at /home/xxxx/domains/ma
XXXX line 45) {“exception”:“[object] (Mautic\CoreBundle\Exception\BadConfigurationException(code: 0): Mauve is missing a required config file at/home/xxxxx/domains/marketing. xxxxx.com)”} {“hostname”:“xx. xxxxx.com”,“pid”:11627}

Steps I have tried to fix the problem:
Check the access rights, and did a cache clear.
