What? The license identifier is a hash of the account ID used to either a) log into SC verification or b) auto-validate with Steam. (which on that part uses the V AppID so isn’t affected by Valve’s changes)
It does not ever change randomly or on different systems, nor are there any “issues” with it.
There are also like 3 other identifier types to use, relying only on one of them is misusing the identifier system.
