Error in start_metshi() Function - Gray Screen and Unexpected Closing

[PSobrevalsAlcaraz]

Hi Joanna,

First of all, thank you for sharing this nice ShinyApp!
I am trying to install it through R, and I've installed everything from the dev branch successfully. But when I execute the start_metshi() function I encounter something odd, the app opens in my browser with the message "" and the logo, but then the screen turns gray and stops working.

The R console shows the following output:

[1] "Adding disk: C:/ to file picker."
[1] "Adding disk: D:/ to file picker."

The warnings seem significant, especially the one involving an if condition error* and the unregistered 'plotly_click' event*. Although the most relevant is the closing metaboshiny*, where the app closes unexpectedly.
*Highlighted them in bold for clarification.

I'm not sure where this is coming from, and I cannot figure it out by myself.
Have you encountered this before? Do you have any suggestions of how to solve this?

Thank you so much for your time and help!
