Warning: preg_match_all(): Compilation failed: UTF-8 error:

Hi, we’re using this plugin of yours quite a lot. And I’m exporting the data from our main site then import to multiple sites. Our only issue is this warning shows:

Warning: preg_match_all(): Compilation failed: UTF-8 error: isolated byte with 0x80 bit set at offset 9 in C:\xampp\htdocs\wp_testing\wp-content\plugins\links-auto-replacer\public\class-lar-public.php on line 369

Is it due to php versioning? our main site is php7.2 and my local php version is 7.4. Any advice to fix this?

Thank you!
