Rshiny pwa, not working anymore

I have a PWA (progressive web app) made in R using shiny, shiny.pwa, shinyMobile and shinyWidgets, among other packages for plotting and designing.
The last modification was in April 2022, and it was working fine until a few days ago. I noticed some misinformation in the app, so I commented out some lines which were just texts, and now the app does not show any plot... More specifically, it does not show anything that is reactive. I don't see any error in the R console when I "Run App" locally, but I see this error (photo attached) in the web Console, saying
Uncaught TypeError: Cannot read properties of null (reading 'name')
in app.js
I did installing the latest R, Rstudio, and installing all the packages and restarted R, but still see the same errors. Any help here would be grateful. Thank you in advance.
