Seeing the access violation Crash while opening the Vlc 4.x.x on Arm64 device

[nkshatri]

- I'm trying to run the Video on VLC 4.x.x Arm64 version on my arm device and seeing that App is getting crashed immediately.
- I tried analyzing the crash and found that its access violation while trying to access the GUI device object and stack is pointing to "libqt_plugin!qt_startup_hook".
- Next to confirm if problem is actually from libqt_plugin, I tried replacing the libqt_plugin from the VLC 3.x.x and able to see VLC is not crashing and able to play the video. Even though all functionality of the app is not present, but it is not crashing.

Wanted to know if anyone able to resolve this error?

Also, I was tried to compile the VLC 4.x.x for Arm64 but its failing, I'm following the steps mentioned at: https://code.videolan.org/videolan/vlc/ ... D-win32.md and using the toolchain: https://github.com/mstorsjo/llvm-mingw/ ... arch64.zip
Are there any working steps Available?

Hi Team,

i m seeing crash for VLC 4.x.x (Arm64/x64) version whenever i try to launch the video directly using vlc (click on video -->open with VLC).

Here is the error i can see:

"Assertion Failed !

Program: ...am Files\VideoLAN\VLC\plugins\gui\libqt_plugin.dll

For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts

Can you please provide pointers here? Looks like its not getting the handle while creating the GUI
