Windows 10: Application crashes when open file dialog appears and a folder is selected

I experience this issue with two programs:- Mozilla Thunderbird: when i'm trying to attach a file to an email, the dialog windows opens and the moment i select a folder the application crashes - ST Cube Programmer from ST Microelectronics: happens the same, when the file dialog appears and i select any folder the application crashesI'm running Windows 11 on an Acer Aspire 3, it's 3 years old now and never had such issues. Both applications have been installed recently 1-2 weeks ago approx. ST Cube Programmer has been uninstalled and installed again but still experience the issue.

Opening a Folder in VC++

Jack28,
I would look into using a FolderBrowserDialog object in your application. This will open a dialog that lets you select a folder. Then use
Code: FolderBrowserDialog1.selecteditem[/quote] to return the output string of the folder into a textbox, set the textbox enabled property to false so that they cannot type in the path, they have to get the path by selecting the folder using the folder browser.
This will endure your program never throws a directory not found exception and crashing itself.
This is what I have always doen and it works quite nicely.

File Open/Save Dialog causing applications to crash

Seemingly ever since the Windows 10 Creators Update installed itself on my computer, I've been having issues when using the File Open/Save dialog. If I try and open a file, save a file, or upload a file to attach to an email, the application that I'm using will crash (whether it's Chrome, Word, Paint etc). Edge, however, works fine and weirdly, Firefox also works fine.

I have been doing some debugging, trying to figure out what it could be, but I'm running out of things to try.

I've tried the following:

• Resetting folder views to default
  
• Enabling "Show all Folders" in Folder View Settings
  
• Starting computer in safe mode (where the dialog would work just fine)
  

I have also run some tests using MS Paint. I downloaded an application called DebugDiag 2, and had that watch the mspaint process to capture the exceptions thrown when the application would crash. These are the ID's of those exceptions:

• 0XC000001D
  
• 0XC000041D
  

Still using MS Paint as my test application, if I ran it as an adminstrator, I was able to use the File Open/Save dialog perfectly fine, but closing the application then reopening as a normal user would then end with the application crashing upon trying to open a file.

Another thing I've noticed is that when I first sign into Windows, I have about 30 seconds where I can open MS Paint, and be able to use the File Open/Save dialog just fine. After that time, if I close the dialog and then try to use it again, the application will crash.

I've read online that this issue is sometimes caused by the File Open/Save dialog trying to show a folder that no longer exists, or is on an unreachable network drive. So with that in mind, I have restarted my computer (getting that 30 seconds of grace when I first sign in) to be able to open MS Paint, and save a new file to my downloads folder, in the hopes that it would update the "last used folder". Unfortunately, this didn't solve the issue.

Is there anything else I can try?
