Can't open IDEA

Hi Guo Yuhao

Did you update an existing version of the IDE, or is it a new installation?

Try the following:

• Uninstall your current version
• Delete leftover IDE directories before reinstallation
• Install the official version for Apple M1 from https://www.jetbrains.com/idea/download to a new empty directory

Alternatively, you can try installing the IDE via Toolbox.

Thank you, Arina Efremova, my IDEA version is not latest.  

reinstall for websit , It's back to normal

Great. Thanks for the update.
