After launching the rlcraft 2.9.2 a few times , some mods don't work !!!

[kiaprom]

forge : after entering the game a few times, i saw that some of my mods don't work. every time i enter the game, more mods don't work after copying the config from the backup folder of the mod pack i had to the folder where the mod pack was inside. this happened! 4% copied without asking questions, then he asked: this file or... exists . what are you doing? i press the skip for all files . in my opinion, a series of files were deleted from the config folder without me doing anything with the config folder. but it worked when i copied the files . BUT i can't do it every time . help
