I have the activation code and tried it, but it doesn't work as I cannot reset the licence because the 2021 disappeared from my "Licenses & Subscriptions" page when I upgraded to the 2022 version.


Hello Oliver Qamili
Unfortunately that`s not possible but you can still use Studio 2021 on the same computer where Studio 2022 is activated as described in this article: https://gateway.sdl.com/apex/communityknowledge?articleName=000018947
Thank you,
