Can't Import Database

My local db php version is at 7.3.2 and the hosting account we are on is at 7.3. When I try and import the .sql file it comes up error with below:

CREATE TABLE wp_revslider_css (
id int(9) NOT NULL AUTO_INCREMENT,
handle text NOT NULL,
settings longtext,
hover longtext,
advanced longtext,
params longtext NOT NULL,
UNIQUE KEY id (id)
) ENGINE=InnoDB AUTO_INCREMENT=110 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci


`#1273 - Unknown collation: 'utf8mb4_0900_ai_ci'`

I tried to do this [How to Fix](https://allthings.how/how-to-fix-utf8mb4_0900_ai_ci-error-when-importing-wordpress-database/), but it didnt' work.
