So sorry to hear about this issue. That is definitely not a typical experience with Adobe applications. Let us fix this for you. Could you please share few more details like:
Operating system you are working on?
When did this start happening? Are there any recent changes made to your system? For example, any antivirus, system updates or web extensions installed recently.
Does resetting Illustrator Preferences (https://helpx.adobe.com/in/illustrator/using/setting-preferences.html) help resolve the issue? Please note that resetting preferences will remove all the custom settings and Illustrator will launch with default settings. You can also take a backup of the folders in case you want to. Location is mentioned in the article.
