I'm started drupal project (core 9.5.2) installing modules manually (it is not good, i know). After the website is deployed in production, I made changes for configuring composer and all worked well.
As new versions of modules come out, I install them through composer. I use composer require (and the module is installed in /modules/contrib) and then I remove the module folder in /modules, clear the cache and everything works fine. I did this with several modules, such as: ctools, icme, panels, slick, symfony_mailer and others. However, when trying to perform this procedure with the webform, things do not go well (error below). I know that correct way would be to uninstall the module and reinstall it with composer, however, I would lose all the forms created, and all submissions already made. Is there a workaround for this problem?
The website encountered an unexpected error. Please try again later.
