The antiquarian book “The History of the Munich Opera” mentions performances in Munich, but without dates:

Among Winter’s works composed for Munich, in addition to the three first mentioned and those designated as major works, the following are also worth highlighting:

the operas “Psyche” (1790, text by C. Mühler), “Salomon’s Judgment” (1809), “Der Frauenbund” (1805, text by M. Babo), and, alongside “Unterbrochenes Opferfest,” the most well-known “Marie von Montalban” (1800, text based on the tragedy by J. N. Komareck by Karl Reger), and the one-act singspiel “Der Sänger und (der) Schneider” (1819/20). Most of the other operas, such as “Castor and Pollux” (1805), “Maometto” (1819), “Ogus,” “The Pyramids of Babylon,” and “J Fratelli Rivali,” were also performed on the Munich stage. In this respect, at least, Winter could not complain of neglect.
