Error: Too many keys specified; max 64 keys allowed

Recently, I’ve updated one of my wordpress plugins on my website. Then I’ve got an error:

There was an error while updating the database tables needed by “My WordPress Plugin”. Detailed error message: Too many keys specified; max 64 keys allowed

Two of my other sites have the same plugin updated but shot no error like the above.

I’ve googled around and found it was an error related to mySQL limitation. Do you have any solution to help?

Thank you.

P/S - My system specs:
Google Cloud
Easyengine version: 4.0.6
Wordpress version: 5.0.1
