RStudio IDE crashes after running a GARCH(1,1)-simulation with Stan (rstan) on Windows 10

Description of crash -

Hi, all,

I have recently upgraded my R version on a Windows 10 machine from 3.6.0 to 4.1.0. I am a frequent user of Stan (rstan). In particular I have a working GARCH(1,1)-code for time series simulations from https://mc-stan.org/docs/2_27/stan-users-guide/modeling-temporal-heteroscedasticity.html which worked well before. I keep on increasing the amount of empirical data available on the input list. After the ugrade of R to version 4.1.0 my R sessions with the Stan-GARCH(1,1)-code on RStudio invariably crash, for no apparent reason, independent of the notebook (equipped with Windows 10) on which I run the R session. Some help in this matter would be much appreciated.

Many thanks.

Cheers, Henk

RStudio 1.4.1717 is recommended for R 4.1. It is the latest release version.

Hi, @EconProf , many thanks for your suggestion to upgrade RStudio to version 1.4.1717. Having done so, my 1930-lines-*.Rmd-code continues crashing when the GARCH(1,1)-simulation with rstan is to be run with a Student-t-likelihood. I will isolate this simulation in order to identify the cause for this problem. Cheers.
