Welcome to the forum Elena, but please not this is an English language forum only.
A quick translation of your question ...
In the activation of Archicad 22 I chose the trial version and not the educational version. As soon as the program is launched it seems that the license is only commercial. At the expiration date will I still be able to apply for a free one-year student license?
Don't wait for the expiration date.
Apply for the student license now.
I am not sure if you can just activate the student license or if you will need to uninstall and then re-install Archicad - I have never had to install an education license.
There is a post here somewhere about running commercial and education licenses at the same time.
This is not the one I was thinking of but ...
