LANShare I can't get it work!

Hi all.
My operating system is Puppy Bionicpup64 (Ubuntu).
I have already installed and used several appImages (GIMP, Cryptomator, other).
But with LANShare I can’t get it to work; after authorizing the execution, the first “click” on it creates the LanShareDownloads folder but nothing appears on the screen.
Can anyone suggest a solution or address me for a correct solution?
Thank you
the same thing happens if I install the last release “.deb”

Since this appears to be a bug in LAN Share, please report it at Issues · abdularis/LAN-Share · GitHub.

ohh ok. I hope will be corrected.
There is a small problem: can’t make login in
but I try again…

Were are you able to report the issue?
