So I have the same issue currently and I made a post about this and it was also pushed onto a solved topic, but it isn't solved. But since this page is a lot more active I'll post my issue here.
I used to have the Hung crash issue and with the latest 436.02 update, instead of getting Hung crashes, I now get gpu removed / updating. However, it's a very weird occurrence since I don't crash in a constant way. I usually crash in game on the ship and it's very constant with the Hung crashes because that's how I would crash too. So it kind of "rename" it self to another error. I have done a DDU clean install of 436.02, however I didn't remove PhysX and Nvidia folder when uninstalling via DDU.
On another note, I posted this on Reddit with weird packet in and out when using the shop. I don't know how to check for ins and out of packets, but I do know it's very bad since I have a USB wifi adapter and it gets broken when there's too much load onto it. When buying packs in game shop, it broke my USB wifi adapter, and also when opening packs. I assume this has to do with server syncing which might be a fix for code:leaf stuff, but that's my guess. However, it isn't as a big of an issue as the crashes since it doesn't ruin games. I feel bad when I play ranked and I crash which has happened maybe 3 or 4 times and there's nothing I can do.
If anyone has an idea on what to do, I'd give it a go. This only happens for Apex Legends, but I have recently started playing less of Fortnite. This hasn't happened in the past until 436.02 driver update, but if I went back on that update I would get Hung crashes, which happens far more often. I'll provide any information if possible
EDIT: I have followed this guide to get more fps. https://www.youtube.com/watch?v=DQ03GRVmsj8
I feel like these are very standard stuff and not like insane tweeks, but it could make or break the game I guess.
