Recovering from Missing Beyond Compare 5 UI

Just a quick note on how to resolve an oddity.

I used Beyond Compare 5 to compare two 2.8 GB files, and when I was done, I closed the application.

Then later on, when I tried opening the application again, it ran due to the process being seen in Task Manager, but the UI was nowhere to be found.

I tried rebooting Windows 11, didn't fix it.

I tried uninstalling and then reinstalling Beyond Compare 5, didn't fix it.

What helped with the recovery was this:
  1. Pull up a command line prompt from within where Beyond Compare 5 was installed.
  2. Execute:
    BCompare.exe /solo /edit
    This pulls up the text edit window of Beyond Compare 5.
  3. From the opened window, pull up a new session.
  4. Save the workspace (name it anything), and then close the application.
Subsequently, activating Beyond Compare 5 was like normal.

Why this happened in the first place? No idea---might be a corrupted state of the UI when it was dealing with the difference of two rather large files [in binary].

Why this could fix? No idea too---but most likely the built-in text editor is a different code path that bypasses that corrupted state processing that stopped the loading of the UI, which allowed the corrupted state to be fixed through the series of arcane steps.

Hopefully this is useful, but I doubt it. Unlike the era of the Neverwinter Nights 2 Texture Bug, modern incarnations of search engines are more like ad-generating machines with additional AI slop (gasp!).

In other words, this is likely to be buried.

And that's the quick note.
