That's great news about the restores. The two VSS settings were defaults throughout Ver3 and now ver4. I disabled them for a few years and I've re-enabled them. All ok in both situations. Nate, it's weird. I'd certainly report the issue to TeraByte Support. Mention the Entry Point Not Found too.
Regarding drive letters in TBWinRE. On the TBLauncher... Tools, Drive Letter Assignments. The letters are probably incorrect. Put a tick in Allow matching Windows drive letters. Find your Win11 Volume label, right click, Use Installed Windows Drive Letters, Yes. Now they should match what you see in Windows. This helps if you use an Explorer in TBWinRE.
I'll have to see if there's an ifw.ini setting for that so that'll it'll reflect the WinRE when I rebuild it.
