R export to sas but cannot open

问题

I export data from R to sas format with package haven. However, when I open my .sas7bdat data. It fails.

library(haven)
write_sas(M, "C:/Users/user/desktop/MERGED_data.sas7bdat")

I provide my data structure below:

Here is the properties.

I double click the data to open in sas, but it fails and provides the information.

Any suggestion?
