Well, yes, we can change windows, by allowing/disallowing SMB1. 
Which might help in detecting whats off..  

I would check 3 things here before this is reported as bug. 

Kerberos/Authentication. krb5.conf, Did you change the : clockskew or renew_lifetime
Set only this : 
[libdefaults]
    default_realm = YOUR.REALM.TLD
    dns_lookup_kdc = true
    dns_lookup_realm = false

;; optinal. 
;    forwardable = true
;    proxiable = true
;    ticket_lifetime = 24h	<< one you can try as LAST option. 
;    ccache_type = 4



Are the pc's connected to multiple servers. Then on these servers run : smbstatus -A
Check these outputs. 

The windows clients, do these have SMB1 still enabled or not? 
And what are the windows eventlogs telling ( post event id and part of description ).

Now, you can try these also. I tested samba 4.9.6 and 4.10.2 on Debian 9. 

    smb encrypt = required
    client min protocol = SMB2
    client max protocol = SMB3
