Answer 1

Try this use get method
Route::get("user/profile_picture","UserController#profilePicture")->name("user.profilePicture");
Route::get("user/bio", "UserController#bio")->name("user.bio");

Answer 2

Just change these routes
Route::post("user/profile_picture", "UserController#profilePicture")->name("user.profilePicture");
Route::post("user/bio", "UserController#bio")->name("user.bio");
to...
Route::get("user/profile_picture", "UserController#profilePicture")->name("user.profilePicture");
Route::get("user/bio", "UserController#bio")->name("user.bio");
done.
