I have Adobe Muse 2018 installed on my computer and use it for several websites. If my Adobe Creative Cloud account is canceled, will it continue to launch and work on my computer?
No. You must maintain a paid ALL APPS plan to keep using Muse.
That said, Muse is end of life since March 2018 and should not be used for current projects because it's outdated. Find other web solutions and re-build your old Muse sites ASAP.
