@liushasha Same problem here !! :-(
When I open the M5burner exe file (last version on m5doc site is M5Burner-v3-beta-win-x64) nothing happens. All I get is a black screen. (The left side of it is ok -shows all the options (CORE, Stick C, Atom...etc)
I did received that blue screen of Windows Defender but clicking on "More Info", you can install it anyway....
But tried also going to Windows Defender page and disabling the apps and files verification (Nothing happened). Tried disbling the AVAST antivirus (nothing again)
Is there a M5burner exe "not beta" working ???
Thanks !

I just installed M5Burner-v3-beta-win-x64 but it simply doesn´t show ANYTHING when it opens. Only a black screen and nothing showing on it ! Tried installing as administrator, downloading 2 times de exe file, cutting off the antivirus and nothing !
Found the 2.5.1 version of M5Burner online and it opened without any problem but there is no way of updating this version further than the 2.5.1 and the version for UI Flow shown in here is 1.9.8 and can´t have a way to get the new one (v 2.0) through M5Burner 2.5.1.
Is there a newer version - not a beta one - that I can download and have all the newer versions UiFlow out there ??
