I guess you need try to remove any special symbols from application name like dots (.) or something and try to launch again. — picolino, Jan 31 '20 at 07:13
my application name is only "Kefi" there are no special symbol. — kefi Kefi, Jan 31 '20 at 07:32
Problem not occur on simulator it only come when we deploy code on real device — kefi Kefi, Jan 31 '20 at 07:33
You can try to delete the bin and obj folder, clean and rebuild again. — nevermore, Jan 31 '20 at 09:56
