fulltextsearch [Bug]: Can't enable "Full text search" and "Full text search - Files" apps after upgrade to v32.0.0 – Error: This app cannot be enabled because it makes the server unstable

Bug description

I would like to upgrade from the stable version v29.0.6 to the development version (GitHub) v32.0.0 dev. I am replacing my stable version with a clone from the project's GitHub fork. When accessing my web page, I am prompted to update various applications to adapt them to the Nextcloud version 32.0.0 dev.

After completing the update, I encounter a server error:

To make it work, I need to disable one of these two applications: "Full text search" ou "Full text search – Files". Once disabled, I can access my web page again.

However, my main goal is to enable full-text search functionnality, which worked correctly in the stable version under the condition that the following three applications are activated:

Full text search
Full text search – Files
Full text search - Elasticsearch Platform

But when I try to activate the "Full text search" and "Full text search – Files" applications together, an error occurs: "Error: This app cannot be enabled because it makes the server unstable".

Sometimes, it doesn't always happen, but I occasionnally get the following message in the app details: "This app cannot be installed due to unmet depedencies: Server version 31 or lower is required.".

Steps to reproduce

Go to apps page
Enable "Full text search" apps and "Full text search – Files" apps

Expected behaviour

All three apps should be activated.

Actual behaviour

Only 2 out of the 3 apps are activated :

"Full text search" and "Full text search - Elasticsearch Platform" OR
"Full text search - Files" and "Full text search - Elasticsearch Platform"

An error occurs when trying to activate the third app: "Error: This app cannot be enabled because it makes the server unstable".

 GET https://yyyyyy.dom/apps/files 500 (Internal Server Error)

Already tested

Installed the app via CLI: sudo -u apache php occ app:enable files_fulltextsearch

Web result

Rebooted the server:

systemctl restart php-fpm
systemctl restart nginx

Removed and reinstalled the applications (both via git clone and official releases).

Additional notes

I suspect that this issue might simply be due to the fact that these apps are not yet compatible with the latest version of Nextcloud. However, I am not entirely sure.

Yeah I guess it's currently not compatible with NC32. I was able to enable the app but it throws errors:

Failed to construct console command 'OCA\Files_FullTextSearch\Command\Configure': Could not resolve OCP\ILogger! Class can not be instantiated
Failed to construct console command 'OCA\FullTextSearch\Command\Check': Could not resolve OCP\ILogger! Class can not be instantiated

@ArtificialOwl the update for the core app solved one of the two errors - but Full text search - Files is still having troubles.
