I need to build an R package for ‘R Under development’ (4.5.0) which could be built without problems for R 4.4.0. However, now I get the error:

• creating vignettes … ERROR
  — neu erzeugen von ‘ocs-vignette.Rmd’ mit rmarkdown

Exited with status 1.

Or alternatively:

• checking re-building of vignette outputs … [19s] ERROR
  Error(s) in re-building vignettes:
  — re-building ‘ocs-vignette.Rmd’ using rmarkdown

Does anyone know why the error message appears? It occurs only with ‘R Under development’.

The same problem occured on different machines.
