Rstudio becomes unresponsive when viewing or autocompleting nested dataframe

[MattZ]

As per the title, whenever I try to view or autocomplete on a nested grouped_df, Rstudio becomes unresponsive. This occurs directly after populating the nested dataframe with nine Bayesian models using brms :

RawN <- RawN %>%
  mutate(model = map(data, ~brm(bf(Values ~ 0 + Group*DOB + SW + WG + (1|Box)),
                   data = .x,
               chains = 3, cores = 3,
               family = gaussian(),
             control = list(max_treedepth = 15,
             adapt_delta = .99),
             save_pars = save_pars(all = TRUE),
             sample_prior = TRUE,
                                       seed = 42,
                                       iter = 20000,
                                       warmup = 19000)))

Windows 10
Rstudio 2023.06.1 Build 524
purrr version 1.02
brms version 2.20.1

Any idea why this may occur?

Cheers,

Matt
