I don't know if this is the best forum to discuss RStudio IDE errors, but here you go...
Some variables are displayed as "NaN B" size in the Environment viewer panel in RStudio IDE Version 2025.04.0-daily+168 (2025.04.0-daily+168).
(Yes, I'm running a daily version of the IDE because I was hoping it would fix the up arrow history bug in the console, but it is still broken)
Screen shot is attached
