(Pre)-Master-Secret TLS decryption not working on Mac

Hello

I'm trying to decrypt TLSv1.2 with reference to the following page.

Using the (Pre)-Master-Secret https://wiki.wireshark.org/TLS

My Environment is following.

Mac : Ventura 13.3.1(22E261) Chrome : 114.0.5735.133(Official Build) (x86_64) Wireshark : Version 4.0.6 (v4.0.6-0-gac2f5a01286a).

Chrome constantly updates ssl-key-log file.

I set SSLKEYLOGFILE path as "(Pre)-Master-Secret log filename" in Wireshark.

But TLS decryption is not working.

The following, encrypted display will appear.

Encrypted Application Data: 7e7b734de5867a290b3429a7794766752e8dfc28f1efbd4aeafeb0c6aa94dc24ee0a9f4b…

Is there any way to verify that Wireshark is referencing the SSLKEYLOGFILE and performing the decryption ?
