[v3] Windows: catastrophic failure on cancel SaveFileDialog
Description
Discussion on Discord: https://discord.com/channels/1042734330029547630/1372320919103475743
When the SaveFileDialog is opened and cancelled or closed the application closes with a catastrophic failure.
To Reproduce
- Use the v3-wails branch for wails,
- Clone the repo https://github.com/eryalito/wails-savefiledialogs-bug,
- wails3 dev,
- Press the greet button,
- Cancel or close the dialog
Expected behaviour
The application should not fail in that way. It should return and error or an empty string.

It works fine on my Windows 10. But I removed the line replace github.com/wailsapp/wails/v3 => ../wails/v3 from your go.mod file. It looks like you're using your own version of wails/v3.
Hi @hkhere. I did this so I could try the latest version on the v3-alpha branch, using the tag v3.0.0-alpha9 works since the change was made afterwards. For reference, ../wails is a clone of the upstream repo (this one) on the last commit on that branch (tested on 3716aca)
@eryalito I see the problem and have reviewed your PR, but I think the changes in your PR are not quite appropriate, so I’ve submitted another PR 4284
Hey! this issue has been fixed (I tried it on alpha.19)
I'm closing the issue now. Thank you @hkhere and @leaanthony
