I am trying to:

List my currently installed plugins in wordpress

Link to a page where the issue can be seen:

none (admin panel)

I expected to see:

a list of all my plugins

Instead, I got:

Fatal error: Call to a member function get_external_repo() on null in /wordpress/wp-content/plugins/sitepress-multilingual-cms/vendor/otgs/installer/includes/class-wp-installer.php on line 2335

PHP Version 5.6.34

I have disabled all plugins in the wordpress database and enabled them one by one.

The problem is caused from "sitepress-multilingual-cms.4.2.5".
As soon as I activate this, I cannot see my plugin list anymore.

All things are updated, including the WMPL plugins.
I have downloaded all WPML plugins also from the website and uploaded it manually via FTP to the server just to make sure.

The WMPL Version overview page shows I am using the latest versions.

Hello @ilkab, welcome to the WPML support Forum!

This may be related to the PHP version of your server. I checked the settings of your server through debug log and saw that some items need attention:
PHP version
Upgrade the PHP to version 7 or higher. This is a practice recommended by the website:

Increase WP memory
Please increase the PHP memory limit to 256mb or more. Currently this memory is set to 128mb.

Currently your server is configured with MaxInputVars = 1000, which is too low and can cause some issues. Please increase this to 10,000. There are two options to do this:
== php.ini file
Open the php.ini file and insert/edit this line:

max_input_vars = 10000

hidden link
== .htaccess file

php_value max_input_vars 10000

Please let me know if it worked for you.

All the best,
