Does this always happen when opening a file or just sometimes? Does the file name have any weird characters?

Thank you for the answer!! It’s always happening both on any .asessts or bundle. File names are like

It used to work, but problem happened after I tried fifth release, which was carshing down from the first time.After I deleted the old version, the new version mentioned that it can't find .NET. I reinstalled the .NET as the window described, but it started to crash too.

Definitely an avalonia issue. I probably won't be able to reproduce this on my computer but I can take a look at what might cause that.

If you only care about viewing, you should be able to get away with just dragging files onto the window you want to open.

I can't see any problems with Avalonia's file picker code. Whenever a multi-file file picker returns, it calls IShellItemArray::GetCount to get how many files were selected, then IShellItemArray::GetItemAt on 0..n-1 to get each file. According to the microsoft docs, GetItemAt only returns an error if an array is accessed that isn't within 0..n-1, which should be impossible since the loop to read files never exceeds n. In other words, it should be impossible for you to get this error. Also, I searched around a bit and didn't find anyone else with this problem. This sounds like maybe a system configuration issue. Are other programs on this computer able to open multiple files at once? I don't think there's really anything I can do to fix this.

Thank you for the answer, I guess I'll have to try other methods.
