Request urgent help in phpmyadmin

There is a problem using Cyber ​​Panel
When downloading a large database, not all of it is downloaded. Some data remains missing, and when uploading it to another database, the download fails.
For example: I downloaded a database that contains 146 tables
When I uploaded it to another database, I found 17 tables in it
And it shows me this error

If you database is so big you have to export it from the command line sometime very big dbs cause issues with the phpmyadmin
