I killed my R studio functionality and I cannot repair the problem.

I use Windows 10 with Rstudio version 1.2.5042 and R 4.0.0.
I am a beginner in R and using R for my thesis work.

I constructed a “quite complex” formula with map function
that I can only run until a too complex change of the formula.
Complex change: if I substitute a categorial variable (5 levels) in my first working formula
by a numeric variable (1-5), R cannot finish calculating.
(First high CPU utilisation of both RStudio R Session and of Qt QtWebenigneprocess,
then only of QtQtWebengineprocess).

The stop button does not work, I have to “kill” RStudio tasks,
I also did a newstart of my PC.
Thereafter, even if I change to the simpler formula again (that worked first),
RStudio cannot finish calculating, anymore.
Only RGui (64 bit) show results.

I tried new installing of my RStudio and R version without success.
Even after creating a new User Profile and after deleting the following files,
nothing seems to work:

  • %userprofile%\AppData\Local\Temp
  • %userprofile%\AppData\Local\RStudio-Desktop
  • %userprofile%\AppData\Roaming\RStudio\Desktop.ini

Only on a new installed PC with my transferred data,
I can run the code until I change the formula, again. Thereafter the same problems arise.

What can I do to establish the initial situation?
Thank's a lot!

Finally, I think the problem is found:
My dataframe (with around 4300 observations) had too many variable columns (almost 1300).
After adjusting the dataframe it seems to work, now!
