After trying to plot something with plot_ly() I got a message " WebGL not supported in internal browser".
Therefore I changed "Rendering engine" in Advanced settings from "automatic" to "desktop OpenGL".
After this change Rstudio does not start and with diagnostics I get the following messages
R session launched, attempting to connect on port 35029...
[11668:12416:1130/165250.196:ERROR:gl_surface_wgl.cc(391)] wglCreatePbufferARB not available.
[11668:12416:1130/165250.196:ERROR:gl_surface_qt.cpp(200)] Requested OpenGL implementation is not supported. Implementation: 1
Successfully initialized R session.
Diagnostics report written to: C:/Users/username/Documents/rstudio-diagnostics/diagnostics-report.txt
I deinstalled and reinstalled the latest version of Rstudio and I deleted the "Rstudio_Desktop" folder which did not solve the problem. I use Windows 10.
Hope someone can help.
EDIT: I forgot to say that I was working from a remote desktop connection.
