Specifically, one user was able to narrow down the issue to OneDrive and a reinstallation of OneDrive using installer from Microsoft website seems to solve the issue.
As I indicated in my response at the bottom of this thread, a safe approach is to use Drag-n-drop facility of VeraCrypt to mount file containers(just drop the file on VeraCrypt UI and it will fill the container file path automatically). No need to manually type the file container path.
Here is a quote of my answer on the Sourceforg thread:
For the issue about "Select File", there is nothing that can be done from VeraCrypt because it is Explorer shell who causes the issue: in the past, I have encountered issues with certain Explorer Shell Extensions that are automatically loaded when using the open file dialog and which cause issues with VeraCrypt. These shell extensions are loaded into VeraCrypt memory space and there is no way to block them from being loaded. In this particular case, it is the shell extension of One Drive that causes the issue.
From security point of view, having foreign dlls loaded into VeraCrypt memory space is not good and so I advice to always use Drag-n-drop facility of VeraCrypt to mount file containers instead of clicking on the "Select File" button.
The more secure approach would be to implement a custom file selection dialog that doesn't use Explorer Shell but this is too much work.
On my side, I don't have this issue on my Windows 11 22H2 with latest updates installed (OS build 22621.1992) but I don't have OneDrive installed.
On your side, do you have OneDrive installed? If yes, can you uninstall it and then check if the issue still remains?
Of course, I will try to reproduce to try to understand the cause.

Expected behavior
Select file... should open a file explorer dialog to select the encrypted file on disk.
Observed behavior
No explorer dialog opens. The program then becomes unusable and interactivity halts on anything clicked in the Veracrypt UI. I must then use Task Manager to End task.
Workaround for now: Manually typing in the encryption file path in the Volume input box and then clicking Mount does work successfully. My hunch is that the Select file... not working is likely due to a recent update on Windows 11 Insider or Veracrypt's file dialog handler might need to be updated? Dunno.
