My minecraft world is not appearing after modding minecraft using tlauncher. please help

so here is the whole story that happens with me and my minecraft world disappear.

*  i was playing vanilla minecraft and it was slow. so i decided to install optimization mods.

* i use tlauncher as default launcher, so i used the modding feature of it to install some mods and to run the mods. tlauncher downloaded forge and fabric.

* after finishing the mod pack for myself, i ran the game but my world disappeared. 

so that is how it happened and i tried some troubleshooting steps which are down below.

* turned all the mods off and just ran the game with forge API turned on.  the world was still gone.

* tried to run vanilla optifine and the world shows up fine and runs normal.

* tried running the forge minecraft that tlauncher provides pre-configured and the world shows up.

* checked the world files and the world is not corrupt.

what could be the issue. the mod pack that i created for myself uses latest forge version and latest minecraft version. but the world does not show up.  but if i run the pre-configured version of tlauncher. the world is fine.  why??? help.

here is the list of the mods in my mod pack and the mod pack mc and forge version.
