Error in ctrl$optimizer <- optimizer[..i] : object of type 'symbol' is not subsettable

[tib-sim]

Hi,
I am getting an error since I updated Rstudio, R and all the packages including afex. When I ran a model that was working before I am getting a error that I did not have before.

Error in ctrl$optimizer <- optimizer[..i] : object of type 'symbol' is not subsettable

object= mixed(Y ~ Cond1*Cond2+ (1+Cond1+Cond2|Subj), data= ds, type=2, method = "LRT", all_fit = T,control=cntrl.lmer)

cntrl.lmer is defined as follows cntrl.lmer= lmerControl(optimizer="bobyqa", optCtrl=list(maxfun=50000))

I am not sure how I can solve it and what it means exactly.

Indeed, the following fails:

suppressPackageStartupMessages(library("afex"))
data("sk2011.2") # data described in more detail below
sk2_aff <- droplevels(sk2011.2[sk2011.2$what == "affirmation",])
cntrl.lmer <- lmerControl(optimizer="bobyqa", optCtrl=list(maxfun=50000))

sk2_aff_b <- mixed(response ~ instruction*type+(inference|id), sk2_aff,
                   all_fit = TRUE, method = "LRT", control=cntrl.lmer)
