Many mods have been impacted by the update, including the all-too-useful Fallout 4 Script Extender (F4SE). As explained on its Nexus Mods page, F4SE is a foundational modding resource that extends scripting capabilities without permanent side effects. A wide variety of mods rely on the project to work at all, so without it, modifying Fallout 4 gets a lot more complicated.
“The 2024-04-25 Fallout 4 update (1.10.980 and later) has broken F4SE and the rest of the native code modding scene similarly to Skyrim's ‘Anniversary Edition’ patch,” F4SE developer ianpatt said in a post. “I am working on an update and cannot currently offer a timeline for its availability, nor whether there will be any critical technical issues that would block an update. Do not email with questions.”

In short, the Fallout 4 next-gen update is a buggy, broken mess.
Players worldwide are experiencing all kinds of issues with the Fallout 4 next-gen update, ranging from broken mod load orders to corrupted saves (some of which have been running for hundreds of hours). PC players are complaining that ultrawide support, a new feature added with the next-gen update, doesn’t work properly, and in the densest areas of the game, the frame rate is still experiencing drawbacks.
Users on Steam Deck have reported having their settings wiped by the update, which is another issue. Also, the creators of Fallout London recently revealed that the sudden drop of the next-gen upgrade has thrown their project into disarray, forcing them to postpone it mere days before it was due to be released.
