Feel free to create a ticket at OBS https://github.com/obsproject/obs-studio and tell them to permanently fix it updating the library (simple enough)
Steps:
librist.dll with the one from the zipThere is a chance that this dll might get overwritten on updates, so you will have to do that probably every time you perform an update.
Also new librist risturl arguments that would usually work like &username=moo&password=xxx need to be implemented by the OBS team. For unknown reason they don’t just take the whole url but seem to parse and process it
