Android Question does not work library New Net library

[aviario]

We have a program in version B4A 6.5 that uses this library to connect to the FTP server of Fillezilla, now we change to version B4A 7.3 and the software does not run. When we try to connect, the program does not do anything

The Version is Net 1.75

the problem must be some library of which I am using, I made a program only with the library Net. 1.75 and it works correctly

These are the libraries that I am using

Thank you
