How not to reload variables in shiny?

Hello everyone,

I am new to R shiny and i am developping an application using football data (data frame of 400 thousand lines).

My application worked perfectly but since i updated Rstudio it does not work anymore and does not recognize the variables i defined in the workspace separately.
I think I have now to define the variables in the application (maybe in the UI file) but the data takes like 15 minutes to load, so i am asking if somebody knows another solution for this.

I hope I have been clear, thank you for your help.

Could you format this into a reproducible example? That is a set of code or rstudio.cloud project that folks can easily get up and running to replicate your issue? Currently, this is only part of a shiny app.
