Octolapse internal server error

new to octoprint and have downloaded a few plugins , went to grab octo lapse and after relaunching in the top right corner my octoprint said " Main Settings Save Error
Unable to save the main settings. Status: error. Error: INTERNAL SERVER ERROR"

so i took a peak at the cmd promt and it also has a few errors:
octoprint.plugin - ERROR - Error while calling plugin octolapse

  • octoprint - ERROR - Exception on /plugin/octolapse/saveMainSettings [POST]

octoprint.util.comm - ERROR - Unexpected error while setting baudrate 250000

I cant enable octoprint or make a profile for it ive tried unistalling and reinstalling but it just wont function any help is appreciated
