rStudio freezing/crashing trying to load modeltime.gluonts

[John Rambo]

Ubuntu 16.x LTS, R 4.0.5, latest packages

While trying 'Option 1/2' to install and run modeltime.gluonts
rStudio freezes and crashes. Doing the same in Win7 works.
But I need it on Ubuntu too.

This works incl. r-gluonts-environment install...

A)
remotes::install_github("business-science/modeltime.gluonts")
B)
install_gluonts()

I have all necessary paths checked (SRC).

library(modeltime.gluonts) <-freezes/hangs
library(tidymodels)
library(tidyverse)

print('It would be so nice...')
stop()

Can someone help me please- I'm already crying?!

SRC:
#Sys.setenv(GLUONTS_PYTHON ='/home/rstud/anaconda3/envs/r-gluonts/bin')
#library(reticulate)
#reticulate::use_python("/home/rstud/anaconda3/envs/r-gluonts/bin/python", required = T)
#reticulate::use_python("/home/rstud/anaconda3/envs/r-reticulate/bin/python", required = T)
#reticulate::use_condaenv("r-gluonts")
#reticulate::use_condaenv("r-reticulate")
#info<-reticulate::py_discover_config()
#print(info)
#stop()
#library(modeltime)
