Hi  
I’m updating from 2021.03 to 2021.06 but the smart freezes in developer  
When I try to open a form it freezes and does not paint the screen

This only happens to me in smart, in NG everything works perfectly

Any idea??

Thanks

The idea is to install servoy 2022.3.1 but when updating, when executing the smart it stayed frozen  
So I was installing versions backwards to see which one did not cause the problem  
until I was able to verify that with 2020.3.3 it works correctly, from that version the smart stays frozen
