Steinberg Nuendo randomly stops reporting %WindowName%


I need urgent help debugging this, to find out what the issue is.

After X amount of time working on a project in Steinberg Nuendo, the %WindowName% title can't read anything anymore. It reports as either nothing using %WindowName%1% or "..." for %WindowName%All%. I'm using the same way of reading the variables as I've done for years.

When opening a new project, the titles come back again.

The latest version of Nuendo is a wreck in terms of stability, but I'm not sure if Nuendo is the culprit or something else.

Is this something known, and what can be the cause of this?

Attaching a example macro.
