Belnder opens for 2 seconds, then closes.

When called, the program first displays a blank command prompt window, followed almost immediately by a blank Blender window. Two seconds later they both close.

I uninstalled Blender, using IOBit uninstaller, which searches for left-over data once a program’s uninstaller has run, and them reinstalled Blender.

This has made no difference, it still closes after two seconds.

Does anyone know what the cause of this might be?

No, can you start Blender from a Command Shell (CMD)?
You can get error messages hopefully, without it is really hard.
Tell us more about your system, OS, GPU, driver, Blender version etc…
