Installing clarion/customer-attribute (1.2.0): Downloading (failed)

I’m trying to run the “composer install” command because i have deleted my vendors folder >_> and get this message:

Autoload error: Vendor autoload is not found. Please run 'composer install' under application root directory.root@localmaschine:/var/www/html/magento

However, the process always aborts with the message:

Info from https://repo.packagist.org: #StandWithUkraine
  - Installing clarion/customer-attribute (1.2.0): Downloading (failed)

  [ComposerDownloaderTransportException]
  The "https://repo.magento.com/archives/clarion/customer-attribute/clarion-customer-attribute-1.2.0.0.zip" file could not be downloaded (HTTP/1.
  1 404 Not Found)

Edit://
I tried changing the version from 1.2.0.0 to 1.2.0 in the composer.lock file. But didn’t help.

Does anyone have an idea what I could do?

Thanks in advance.
