I am running a RMarkdown report which has many plots at times I get this error “! unable to start png() device”. At times the report runs without any issues and at times it breaks at different chunks. Does anyone know what could be causing this? I am using RStudio installed in the HP computer.

I have tried searching for the solution by creating a working directory but still it fails at times and runs without any errors at times.

Thank you!
