So

so is the thity-fourth video uploaded by novelty. It was uploaded on February 17, 2021 with the description, "VE8gV0hPTQ".

Description
The same odd jumbled audio heard in previous videos plays as our protagonist is standing behind an open window, looking out to the grass below. In the background some sort of wall or tall fence can be seen. Loud thumping sounds can be heard but it's impossible to tell what caused them.

Analysis

 * Decoding the description with base64 gives you the message, "TO WHOM". "To whom" is the first two words of the phrase, "To whom it may concern", which can be found in business communications meaning that the message is intended for whoever should read it.
 * Novelty himself commented in the comment's section, "i wont let me".
