Failing to decrypt kerberos AP_REP with wireshark

I'm trying to decrypt kerberos traffic with wireshark for the learning purposes. My process of following:

1. First I retrive keytab for the test user with kadmin

kadmin.local:  ktadd -k vdzh-fin.keytab [email protected]
Entry for principal [email protected] with kvno 15, encryption type aes256-cts-hmac-sha1-96 added to keytab WRFILE:vdzh-fin.keytab.
Entry for principal [email protected] with kvno 15, encryption type aes128-cts-hmac-sha1-96 added to keytab WRFILE:vdzh-fin.keytab.
Entry for principal [email protected] with kvno 15, encryption type aes128-cts-hmac-sha256-128 added to keytab WRFILE:vdzh-fin.keytab.
Entry for principal [email protected] with kvno 15, encryption type aes256-cts-hmac-sha384-192 added to keytab WRFILE:vdzh-fin.keytab.
Entry for principal [email protected] with kvno 15, encryption type camellia128-cts-cmac added to keytab WRFILE:vdzh-fin.keytab.
Entry for principal [email protected] with kvno 15, encryption type camellia256-cts-cmac added to keytab WRFILE:vdzh-fin.keytab.

I guess it randomizes keys in keytab and incrementing kvno, but then, I'm authenticating with this keytab.

In second tab I'm starting tcpdump:

vdzharkov@dell-ku:~/work/logs/ipa_krb_tests$ sudo tcpdump host 192.168.5.19 -w fin.pcap

Then I authenticate:

vdzharkov@dell-ku:~/work/logs/ipa_krb_tests$ kdestroy -A
vdzharkov@dell-ku:~/work/logs/ipa_krb_tests$ kinit -kt vdzh-fin.keytab vdzharkov

After that I'm trying to decrypt the enc-part of the AS_REP, but to no success:

vdzharkov@dell-ku:~/work/logs/ipa_krb_tests$ tshark -r fin.pcap -K vdzh-fin.keytab -w finout.pcap

I also tried the same via wireshark gui with Preferences -> Protocols -> KRB5, then checked all options and supplied the keytab file, but to no effect.

Versions:
TShark (Wireshark) 3.6.2 (Git v3.6.2 packaged as 3.6.2-2)

Funnily enough I can decrypt the TGT with krbtgt principal keytab:

So I have two questions:

1. Am I doing something wrong?
2. Maybe there are some library alternatives to try to decrypt kerberos encrypted blobs captured with wireshark?
