We understand that encountering technical issues can be frustrating. I hope Monika's suggestions helped resolve the problem. If not, kindly share the memory dump by uploading it to Google Drive/Dropbox/etc. and sharing a public link to it, so we can check it with the product team:
Steps to collect Memory Dump on Windows :
Open Task Manager
Right click on Adobe Illustrator task process
Click on Create Dump file
Once the dump is created, there will be a .dmp file created in temp folder(Location will be visible on dialog once dump is completely written)
Steps for macOS:
By default, macOS disables core dumps for most applications. To enable core dumps, you'll need to execute the following command in Terminal:
sudo launchctl limit core unlimited
After the crash, macOS typically generates a crash report which can be found in the following directory:
~/Library/Logs/DiagnosticReports
Also, during crash, a pop-up dialog appears. Click Report... to save the report to system reports. You can use the following steps to locate the system reports in your system:
Click the launch pad and search for Console.
In Console, click System Reports on the left pane.
Search for Crash report having the filename with a prefix as Adobe Crash Reporter_YYYY-MM-DD where YYYY-MM-DD is the date on which the file is saved.
Right-click on the report file and click Reveal in Finder to get the logs which can be shared.
