Hi 
I ve been working on sonic Pi this summer , but since yesterday, I can not boot the software 
I ve found many tricks on git and on this forum (change server ports, booting on asio4all…) but nothing corrects the error… If someone has an idea of what is going wrong … (here is the boot error report ).
Thank you so much.
