GLOSSA not working with shiny v1.11.0 due to shinyWidgets incompatibility

Summary

GLOSSA currently does not work as expected with shiny version 1.11.0 or later.
This version was released on June 24, 2025: https://cran.r-project.org/package=shiny

The user interface may appear blank. Plots may not render after uploading data. There are no error messages, which can make the issue harder to spot.

The cause is a change in shiny that affects how it interacts with shinyWidgets, which GLOSSA uses in its interface.

The issue has been reported to both shiny and shinyWidgets:

• pickerInput doesn't work with shiny v1.11.0 dreamRs/shinyWidgets#741
• radioGroupButtons() from shinyWidgets broken in Shiny 1.11.0 – “Unexpected input value mode: 'undefined'” error rstudio/shiny#4244

Temporary fix

Until this is resolved upstream, we recommend downgrading shiny to version 1.10.0, which works:

remove.packages("shiny")
if (!requireNamespace("remotes", quietly = TRUE)) install.packages("remotes")
remotes::install_version("shiny", version = "1.10.0")

After installing, restart R and launch GLOSSA again.

We hope this helps in the meantime.
We'll update this thread once the issue is resolved.

This issue has already been addressed in the following pull request: rstudio/shiny#4243

The fix has not yet been released to CRAN. In the meantime, if you'd like to use shiny >v1.11.0 with GLOSSA, you can install the development version of shiny directly from GitHub.

We'll continue to monitor the CRAN release and close this thread when the fix is published on CRAN.

The issue has been resolved in shiny v1.11.1, which is now available on CRAN: https://cran.r-project.org/package=shiny

Thanks to everyone who reported and tracked this! Closing this issue.
