Sounds like you either made a mistake while installing or installed conflicting mods. If you saved or auto-saved the progress while this mod was actually installed, then it is unlikely to be compatible with the game without this mod installed. Therefore, if the progress was saved with this mod installed and works after you uninstalled this mod, then you may not have had this mod installed. If you had a progress from before installing the mod and completely uninstalled the mod(or extracted a new Strive folder) and not simply deleted the mod folder, then you should be safe to play.
