I've been trying to produce optics figures using the pst-optexp package in latex, however something has gone wrong meaning I can't compile anything in latex now using texworks and miktex. I'm working on Windows 10 on a Dell XPS 13.
I've had a few problems with the package and Miktex previously, e.g. having to enable write-18 on the Miktex extension after errors. I found it easiest to get pdf output to look as intended in the package manual by compiling in latex, running dvips and sp2pdf as so on the commmand line:
''' latex test.tex dvips test.dvi ps2pdf test.ps '''
This worked better than compiling with Xelatex, which is the recommended. However, all of a sudden without any changes I can no longer compile with the latex, pdflatex or xelatex commands at all, both on the command line or in the texworks own compiler. I get the error:
Sorry, but latex did not succeed. The log file hopefully contains the information to get MiKTeX going again: [path to log file]
When viewing the log file it reads the following:
latex test.tex 2020-01-02 11:59:06,970Z FATAL latex - invalid stoi argument 2020-01-02 11:59:06,970Z INFO latex - finishing with exit code 1
I assume as a similar term exists in C/C++ that this is a problem with a config file in Miktex, however after uninstall and reinstalling I get the same error trying to compile with any of latex,pdflatex or xelatex.
What does the 'invalid STOI argument' mean in this context, and/or how could this be fixed?
