An unhandled exception thrown on occ fulltextsearch:test

After updating one of the components, the Nextcloud log is flooded with messages. Unfortunately, I didn't notice the error right away, so I can't narrow down the actual problem.
What is certain is that a occ fulltextsearch:test used to work and now the following error (which I also find in the log) occurs:

An unhandled exception has been thrown:
Error: Failed opening required '/var/lib/nextcloud/apps/fulltextsearch/lib/AppInfo/../../vendor/autoload.php' (include_path='/usr/share/webapps/nextcloud/apps/news/vendor/pear/net_url2:/usr/share/webapps/nextcloud/3rdparty/pear/archive_tar:/usr/share/webapps/nextcloud/3rdparty/pear/console_getopt:/usr/share/webapps/nextcloud/3rdparty/pear/pear-core-minimal/src:/usr/share/webapps/nextcloud/3rdparty/pear/pear_exception:/usr/share/webapps/nextcloud/apps:/var/lib/nextcloud/apps') in /var/lib/nextcloud/apps/fulltextsearch/lib/AppInfo/Application.php:54

The file /var/lib/nextcloud/apps/fulltextsearch/vendor/autoload.php really does not exist in the file system and also not in the package!
My Server configuration is: nginx 1.20.1 (with php-fpm 8.0.12), nextcloud 22.2.0 and Full text search 22.0.1

I hope for your support!

Reproduce occ fulltextsearch:test with the reported Nextcloud and Full text search versions, then inspect lib/AppInfo/Application.php around line 54 and the packaged vendor contents. Trace why vendor/autoload.php is absent from /apps/fulltextsearch; done means the command loads the app without the unhandled exception.
