Testing this ciphersuite with openssl, decryption worked as expected:

openssl s_server -cipher  PSK-AES128-GCM-SHA256 -nocert -psk 123456 -tls1_2
openssl s_client -psk 123456 -connect testvm:4433

Openssl is 1.1.1 on both ends and Wireshark is v3.2.6. I suspect your issue is elsewhere, and not with Wireshark. You mention https, but TLS is not https... https uses TLS, but it also implies that http protocol is in use.
