We are getting an error message when we are loading our .aip file on Adobe Illustrator that says: "Can't open the illustration. The file is locked or in use." ID:-54
Approaches (we followed to resolve this issue) :
Uninstalled and reinstalled AI several times.
We have checked the OS dependencies and verified with latest OS as compatible with AI.
We have created plugins again and tried to load same in illustrator but problem remain same.
We have rechecked and updates some build configuration but same issue again.
We have verified the path of output folder and checked with via doing rename also.
We have set the breakpoints also in our code for debugging purpose.
Checked the access privileges also.
We have checked with sample SDK project also. We have generated the .aip file after doing the build process on Xcode and tried to load on AI but same issue happened.
