Unable to change view of camSchnappr main window, dependency loop in renderPick

In the camSchnappr Main Window I can get approximately one update before the perspective will no longer change. Selection of points is possible but inconsistent. The errors dialog shows a cook dependency loop in /project1/camSchnappr3/main/renderPick/eval2

Windows 11 build 26200.8246, TD build 2025.32460

Maybe unrelated, but if I try to resize a column in the Errors dialog, the column disappears.

Using a stock .obj did not change anything. Tested with NoMachines (remote desktop) disabled at boot, to no effect.
