Forced Trailing Slash Removes After Cache Primed by Comet Cache

I was using Comet Cache as it was giving me very good results in speed.

All URLs of my website need to have a forced trailing slash [/].

I have fixed the problem in my .htaccess file too.

Trailing Slash comes when I delete my cache. But when the cache is primed. Again the pages are loading without trailing slashes too.

Example, 1. example.com/krishna/ [This is also loading.]
2. example.com/krishna [This is also loading.]

I want the 2nd one to be redirected to the first one. Everything seems okay in .htaccess, I’ve tried a lot of plugins to do this still failed.

I am using Google Cloud Bitnami WordPress.

Here is my htaccess if you need it: https://pastebin.com/p24BAgU5

I have tried WP Rocket same issue persists. No issue using LiteSpeed Cache, Cache enabler.

Please, developers, explain me in simple language. You are my last hope ??
