Software not working on one user when ASTER is on

[Vttr]

Hi, firstly I have to say aster is awesome in general allowing me and my brother to work separately.

But I do have a problem that appeared recently and it is really bothering.

I have installed a software “Substance Painter” recently,
When I turn on ASTER, the software doesn’t open on one of the users, it only opens on admin account.

It was installed on second user (not admin), I have tried reinstalling it, restarting computer, updating it and nothing fixes it.

I checked and the second user can open the software without any problems when Aster is OFF,
but when it’s ON second user can’t open it.

Problem shortly: software only opens on first user and doesn’t on second (no errors displayed it just doesn’t open)

What can be the problem? And how can I solve it?

Thanks in a advance!
