Critical error with the latest (and older) version!

Hi there,

with the last version as well as with the v3.3 and the last wp version, the following http500 error pops up:

[Thu Mar 31 17:18:28.646648 2022] [proxy_fcgi:error] [pid 89773:tid 140039019296512] [client xx:0] AH01071: Got error 'PHP message: PHP Parse error:  syntax error, unexpected ')' in /home/xxx/domains/xxx.co.uk/public_html/wp-content/plugins/language-switcher/includes/class-language-switcher.php on line 984\n'

The problem lies in those commented lines of code. Without those, the plugin seems to work: https://imgur.com/a/bBOTQ6w
