Logic Pro X--Boesendorfer piano not sounding? [but steinway is]

Hi Logic folks For the past 8 years since I got Logic X I've been using the Boesendorfer piano to create my scores. I did a lot of work in February 2023 on 10 pieces, but not since.

Opened up my files here in July 2023 to find that for some reason the Boesendorfer piano software instrument isn't creating sound. When I switch it to Steinway, it works.

Does anyone know what might be causing this, or how to fix it? I haven't uploaded / downloaded / changed -any- settings since I bought Logic in 2015.

While I could go through ALL my scores--now numbering in the hundreds--and change the piano instrument to Steinway, 1) that's a ton of work and 2) I much prefer the Boesendorfer sound.

Screenshot attached; thanks for any tips.
