You can use this regex

(.*?;){10}(.*?);

Explanation
(.*?;) - This sequence captures everything before the ; character lazy . {10} - This is a quantifier, here it expresses that the previous sequence must be captured 10 times.
(.*?); - Then after the tenth repetition of the .*?; sequence the second catch group is placed to give match in the content after the tenth occurrence of ; .

Note: It is worth remembering that the content you want to capture is in the second capture group of this regex, not the first.
