Thanks for your post and welcome back to the Nokia forum.
We are really sorry for this inconvenience.
In order to fix this issue, I would advise you to check if your phone's software is up to date via this link, enter *#0000# on your keypad to display your current version.
If your phone needs to be updated, connect it with Nokia suite and click on the green arrow icon. Any available updates will be listed here.
If the problems persists, I would suggest you to perform a soft reset on your phone. Enter *#7780# on your keypad, default lock code is 12345.
If your phone still can't open easily folders and apps, I would invite you to perform a hard reset. First of all, back up your data using Nokia Suite (Tools > Back up). Once your data is fully backed up, type *#7370# on the keypad. Default lock code is 12345.
The hard reset will dellete all your personal information, that's why a back up is very important.
Let us know how you get on and feel free to post any other questions you may have.
