Lỗi target uses an invalid compiler run aborted năm 2024

Hi, I'm having trouble when I'm trying to run regular expression code. It compiled fine but when I run it in CodeBlocks I'm getting this error

terminate called after throwing an instance of 'std::regex_error' what[]: regex_error Aborted [core dumped]

Here is the code [taken from //www.cplusplus.com/reference/] As you can see it work fine on cpp.sh. And yes I did enable C++11 support. Anyone know what the problem might be?
