Fault when installing plugin in WP 6.0.2

I can't install the plugin through an upload of it, because when activating it gives the following error message:

"Parse error: syntax error, unexpected end of file in /var/www/html/wp-content/plugins/MistPlayerWPPlugin-master/mistplayer.php on line 204"

I don't know what to do about this, I'm not savvy enough in PHP.
