I think it has something with the certificate, if you look at the error it states "Error building X509 certificate of byte array" so i really couldnt know what is wrong as this is out of patch scope but try everything again following instructions or try reinstalling or re-downloading esys with lite data.

I forgot to mention, my CIC was euro version and trying to activate for Taiwan map, I did passed the first step, CIC rebooted within 10seconds and all FSC cleared.
However, I failed to load new signed FSC with esys 3.28.1 and it had the X509 error as I posted previously.
Was that because I changed the country to TW?
Or it's simply an esys issue? Too new to support CIC?
