Parse error: syntax error

Hello,

I have a website with the following problem:

Plugin kan niet worden geactiveerd omdat hij een fatale fout veroorzaakt.

Parse error: syntax error, unexpected ‘.’, expecting ‘)’ in /home/ateconnl/public_html/web/wp-content/plugins/mollie-payments-for-woocommerce/includes/mollie-api-php/vendor/autoload.php on line 15

Everything is up to date, I tried deactivating all other plugins, that didn’t work sadly. Does anyone else have these problems?
I have it since the update to 4.0.1 today.

Best regards
