pandoc with tinytex stops working after Windows update

[ggrothendieck]

Yesterday running pandoc from the Windows cmd line with a tinytex installation was working on my Windows 10 machine but today after a Windows update it failed with a message about the version of an .fmt file. Running this from R:

library(tinytex)
reinstall_tinytex()

fixed it. I am just posting this in case others have the same problem.

Thanks for sharing the solution!

I guess tinytex:::refresh_all() might fix it, too.
