Loadlibrary failed with Error 87: The parameter is incorrect

78 views (last 30 days)
Dear Matlab support team,
Since I recently upgraded to R2020b, I keep getting the error message "Loadlibrary failed with Error 87: The parameter is incorrect", and then Matlab crashes. With R2020b and R2020a, this happens immediately when I start Matlab. With the much older R2014a, I get the same error message soon after starting an m-file. Prior to upgrading to R2020b, everything worked perfectly fine with R2020a and all earlier releases.

I was able to resolve this issue by running the command opengl('save','software') BEFORE clicking OK on the error dialog window.
