Can't open R scripts

I just installed 2024.09.0 Build 375, and I have suddenly been unable to open R scripts from RStudio. If I go to File -> Open File, navigate to where the script is, and select it, it hangs for a minute or so and then says "The system cannot find the file specified ." If instead I navigate to the file using windows explorer and double click on the script it opens just fine.

I'm using my work computer and trying to access scripts on a shared drive. Any ideas ?

I have the same issue when using Windows network shares (SMB). This is a bug introduced in the latest RStudio release.
It appears to be related to the following commit in RStudio:
Fix file save/load issues in Desktop with certain folder combinations

particularly the normalizeSeparators function in
src/node/desktop/src/core/file-path.ts

now appears to "normalize" the double slash network address prefix to a single slash when loading or saving files.
The open/save dialogs still recognize the network addresses, but the when actually opening or saving scripts (and possibly other files) on a network drive using the double slash or double backslash prefix.

I was only able to cure this by rolling back to an older version of RStudio

Ugh so frustrating that we can't just trust the latest version.
