R Visual returns error and doesn't render when logged in as end-users

I have an R visual that works on Desktop as well as Service when I'm logged in as myself (admin and no RLS implemented). However, when I log in as a user, the R visual returns an error, saying the following:

Loading required package: ggplot2 Loading required package: magrittr Attaching package: 'ggpubr' The following object is masked from 'package:cowplot': get_legend Attaching package: 'gridExtra' The following object is masked from 'package:dplyr': combine Error in aggregate.data.frame(as.data.frame(x), ...) : no rows to aggregate
Please try again later or contact support. If you contact support, please provide these details.

I've made a table visual that contains the exact same fields and it returns data, so there's something going on with the R visual. How do I triage and troubleshoot this? I've found R visuals extremely problematic the past month with this error and I'm lost in terms of what to do. Any help would be much appreciated.
