This was on “Microsoft Edge Version 152.0.4191.53 (Official build) (64-bit)”.
I also tried on Firefox 154.0.1 (64-bit). I get the same additional backslash when using the search box:
Thanks, that’s a very useful find. The leading backslash would explain why the restore completes “successfully” but matches no file — the path submitted from search is not the same as the path selected from the tree.
Since you can reproduce it in both Edge and Firefox, it sounds like an ngclient UI issue rather than a browser quirk. For now, the safest workaround is to select restore files through the tree view instead of search. If you’re able to, please keep those screenshots/request details handy; this is exactly the kind of comparison needed for a bug report/fix.
