There are statistics, how many people updated to the version of Kaspersky Internet Security 18.104.22.1685(d) that was in September 2019? (according to these data https://github.com/aws-amplify/amplify-js/issues/3985)
I ask, since there is still a problem in February 2020: https://enota.club/threads/bag-v-skripte-kasperskogo-main-js-kotoryj-lomaet-sajty-kis-ns-getcommandsrc.1547/
ns.GetCommandSrc is not a function
The scale of the bug is interesting, how quickly did you fix it and how many people installed it?

Please clarify what is the currently installed patch for the product on the PCs with the issue (main KIS window - Support icon - Applciation version - must be 22.214.171.1245(h))?
According to our information the issue must be fixed in the patch H for KIS 2020 and in the patch L for KIS 2019.
Patch H is fully released, so please update bases again, reboot and retest the issue.
Please inform me about the results.
