@manuelbl happens to me all the time, no worries 
@ivankravets indeed the change in the post I linked above and that manuelbl highlighted is not in this update. seems it only updates the version of openocd, which in turn has some breaking changes explained by the openocd devs in the issue in github I linked above.
Changing main.py fixes uploading, but there’s still a fix necessary for the call of the debugger. Supposedly it is the same fix, but I was unable to find where the debugger is acutally called from.
