Hi All
I have an issue with the exam enviroment AppImage. when opened i get a blank white screen
if ran via terminal i get the following response
“./Applications/Exam.Environment_1.5.0_amd64_ddc96526f5e4865680e286ae39930e67.AppImage
** (exam-env:4385): WARNING **: 15:17:24.704: atk-bridge: get_device_events_reply: unknown signature”
other AppImages work as expected
any advice on this would be greatly appreciated
Thanks

unknown signature”
Did you generate a signature and copy/paste it into the app?
When opened there is no text at all so no where for me to enter the signature generated
Do you use a VPN or firewall or anything like that?
I do however i have just tried with both vpn and firewall disabled and still exactly the same

Which operating system and version?
EDIT: aa.. “CachyOS” is your OS?
yes CachyOS is my os its rolling release so doesnt really have a version number as such
That was my concern its unusual that other AppImages work perfectly but this one doesn’t
this usualy indicated a graphics driver issue but the system and all drivers are up to date
i am currently working out how i can install this from source maybe that may help as i can not find this on any repo or the AUR
if i can get it working another way i will update

I don’t think this app is open source
you can try to write to support@freecodecamp.org with the details of your system
Ok I see you were already on to this.
Maybe a Windows emulator?

I have a similar problem:
(same on my laptop running fedora 43 and my desktop with fedora 42)
$ ./Exam.Environment_1.6.0_amd64.AppImage
