Screenshot showing error message

I have successfully used KDiff3 with TortoiseGit on Windows for years. 

Unfortunately, Kdiff3 1.11.* breaks the integration. When requesting a diff of most files, an error dialog appears that says "Opening of Files Failed". See attached screenshot. By most files, it happens to about of 80% of files - ever so often one works. I have not discerned a reason as to why.

Reverting to KDiff3 1.10.7 resolves the issue.

STEPS TO REPRODUCE
1. Install TortoiseGit on Windows 11 (I'm using 2024H2)
2. Checkout a Git repo
3.  Modify a file
4. Right click the file, select TortoiseGit | Diff.
5. See error message

I have setup KDiff3 following the TortoiseGit instructions here:

https://tortoisegit.org/docs/tortoisegit/tgit-dug-settings.html

Meaning, the command line used to run KDiff3 is:

C:\Path-To\kdiff3.exe %base %mine --L1 %bname --L2 %yname

Sounds like 486782 impacts all three way compares.
