This is caused in fact by a correct unittest assertion in
format.d:
f = FormatSpec("a%%b%%c%");
w.clear();
assertThrown!FormatException(f.writeUpToNextSpec(w)); <-- here
assert(w.data == "a%b%c" && f.trailing == "%");
You can add std.Format.FormatException to the Exception Settings
(Debug -> Exceptions) and untick the Thrown checkbox.

Works fine for me (Linux x86_64, DMD 2.069). Which version are
you using exactly? Also, are you sure you're not accidentally
running an outdated executable, or your executable doesn't
actually match the code you posted? It doesn't invoke format at
all.

Are you running this in VisualD plugin? This is the only place I
get that exception. Running it from the command line works as
expected on 2.069.1 win32
