Unable to connect to Helper...

Hey,

I opened Musecore today and I wanted to update it but I had this message "Unable to connect to Helper...". So I deleted all the muse core files on my computer, download it again from your website to be sure to have the last version. Then I deleted the com.muse.museservice file from Macintosh HD/Library/PrivilegedHelperTools folder and I gave Muse Hub permissions for Full Disk Access in macOS system preference as indicated here -> https://musehub.zendesk.com/hc/en-gb/community/posts/8485124416413/comm…

But still it's not working for me...I have the same message. What can I do ?
