Freeze on start up, multiple dpinst-amd64 processes

Good morning
I installed arduino ide 2.3.3 in a practical work room with the alluser option.
When the IDE is started by a user (student) who is not an administrator, the IDE freezes. I see that it creates dpinst-amd64 processes in a loop.
This executable is in the user profile created when the IDE starts. It seems to be blocked by the firewall. How to get around the problem?

A couple things might be for sysad to give your session admin privs to allow executables. Or, tell the sysad to install the IDE for all users (allowing IDE instances adequate permissions).

We don't have a sysad. User authentication is done by an LDAP request.

Are there operations to do so that the executables and libraries are common and not in the user profile, as should be the case with an installation in /allusers?
