Update: Richard has been found! The creator Gushiavo finally understood what I desired and I acquired the file today. I will not make it public, as Steam will take it down as it unintentionally crashes games, but if you're interested, shoot me a message and I will send you an unlisted link so you may enjoy Richard. Thanks to everyone involved in the hunt!

Its been deleted for who knows how long, sometime after the month of May this year, but I would very much like to be in possession of it again. It was unique in the fact that if you killed the Richard NPC, the game would crash instantly, hence my friends and I abused that power, by say, placing a Richard in front of ourselves before imminent death. (Its also quite comical).\

Its full name was "Richard Watterson (The Amazing World of Gumball) (Playermodel and NPC)". All I have to go off of is an old Discord embed that has most of the name, but is cut off after 'Playermodel'. It was published on April 12, 2022, sometime around 8:12PM if that helps.

Here is the old link to the workshop item: https://steamcommunity.com/sharedfiles/filedetails/?id=2793532309 (now an error)

To check if one of you happens to have this old addon on your computer, to find it, go to Steam/steamapps/workshop/content/4000 -- and then you're looking for a folder called "2793532309".
Additionally, you can check :

• Your cache folder steam/steamapps/common/garrysmod/garrysmod/cache/workshop/
  
• Your addons folder: steam/steamapps/common/garrysmod/garrysmod/addons/
  
  In your addons folder, the filename would be (approximately) "richard_watterson_(the_amazing_world_of_gumball)_(playermodel_and_npc)_2793532309.gma".
  
  The model is from an old CN game called "Formula Cartoon All Stars", and can be found online.

  I am also interested in contacting the original creator of this addon, but I cant remember his name as its been so long, but I'm sure if anybody has the file its him. If you're out there, please re-upload Richard Watterson! (And specifically, I would like the version that crashes games)
  
  (Update: I found the creator, Gushiavo_N2, but he is from Chile, and thus its been quite difficult trying to explain what I want to him. I have tried for several days and asked his friends who do speak more english, but to no avail. I hope eventually he will understand, but for now, I must still resort to waiting for someone to find the file...
