I made some edits. Hopefully they were meaningful changes to reflect what you said.

I would suggest taking it apart and try putting the screw into the receiving hole while unbuilt to see if the screw still fits properly with no obstructions. It could be just slightly off when you put it back together causing friction.

I wouldn’t worry to much about taking the foam out. You will more than likely need to just wash it by running soapy water through it or dumping it into a soap bath and then I would use a fan to dry it.

Sorry I don’t.

You have to remove the bottom to unscrew the top from the inside.

I have one slight problem. I opened my remote, now i cant put it back together. The clamp near the charging port just wont get back into place. Nothing is broken. i checked, all clamps are there, but this one just wont slide back in to let me close back the remote. Any tip ?

I would double check the female Clamp end on the bottom part. You my have broken the receiving end of the clamp.

Thank you for the reply. Sadly both of clamps were ok. I managed to fix by bending the male clamp in the outside position. Also, the female clamp was made of aluminum, so breaking it was impossible. I finally closed it somehow, but it still has a little wiggle on the sides. Well, thats about all that can be done.
