Sorry to hear about the difficulties you are facing. Could you please provide more detail on what’s going on when you try to resize the image?
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. Is the issue related to a specific document? If yes, could you please share the document with us? You can upload it to the Creative Cloud (https://helpx.adobe.com/in/creative-cloud/help/share.html) and share the download link.
Also, please try resetting Illustrator Preferences (https://helpx.adobe.com/in/illustrator/using/setting-preferences.html) and let us know if that helps to 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.
We’re here to help, just need more info.
As I (mis)understand it, there is no Bounding Box.
Just to make sure: if the View dropdown list says Show Bounding Box, click it to show. If it says Hide Bounding Box, leave it be.
And what Shristi said.
