Error: Matomo is already installed. Original error was "Mysqli prepare error: Table 'matomo.matomo_option' doesn't exist".

Hello, i had an issue where i wanted to update portainer so i downloaded the backup first but it not seem to have successfully downloaded and i only noticed that after the update, all containers were still running but i couldn't manage the stacks within the new portainer installation due to the error "this stack was created outside of portainer, control over it is limited"

Now i copy the env info etc shown in the running containers and make a new compose file out of it to add in an new stack.

Now i tried to do this process with matomo, which then after visiting the site caused following issue:

There are no erros shown in matomo or database logs, i guess i somehow need to set it so it uses the matomo files from the existing installation and not try to start a new installation process; i don't know how to do so tho.

Note: the go back to matomo just refresh the homepage on which the error happens, statuscode in netrequests is 400

Here the docker-compose.yml file:
