[R] Shiny debug mode- reort a bug R version 4.0.2

[Mani Solimani]

DearR-help Community,

 

since Iupdated the R V.3:6 to R.V4.0.2 I have the following problem:
It might be the problem of R, if the same pack worksunder V.3.6 and suddenly not in V.4.0.2.

If I create an app in RStudio,  and then change into debug mode with "browser()", my R aborts.



I cannot see why? The problem did not exist as I usedR V3.6 3 days ago. For instance, as you can see in the following, my collougeuses still R V3.6 and the debug mode works well.
