I developed my workflow on STUDIO V 2020.4.1 and it was runnning all good , then it had an automatic upgrade to STUDIO PRO , now I m unable to run my code

The workflow I v developed on studio 2020 isn t working on STUDIO PRO 2020 , I can t run the file anymore. Also I didn t migrate to studio Pro , I think it was automatically done. To run my code wht shoud I do exactly : comme back to studio or configure studio Pro ? For now Studio PRO demand to be connected to orchestrator although I didn t publish my solution on UiPath cloud
