Try a 32bit Chrome browser as Ajax (C&S) does not support 64bit recording. (ref: LR 12.53 PAM)

Note: from the LR 12.53 readme:

Support for these protocols will be discontinued in upcoming versions ofLoadRunnerand Performance Center. We recommend that you do not use these protocols for new scripts.
* Ajax Click & Script
Tip:You can migrate your existing Ajax Click & Script scripts to another Web protocol such asTruClient - WeborWeb - HTTP/HTML
