The never-ending loading screen
I recently bought a brand new laptop and reinstalled the whole game from scratch on it. The loading screen just stays on forever and eventually I have to open Task Manager to get out of the game. I've read other threads about this issue and have followed a lot of the advice there. I don't have any mods installed. I've deleted the thumbcache file, totally deleted OneDrive from my computer (not that I ever even activated it on my new machine), turned off various gaming settings in Windows, repaired the game through the Origin app, and completely removed and reinstalled everything twice. I have no idea what else I should do at this point. I'd love to hear any ideas. Thanks.
MadameQCat If the path to Documents is C:\Users\your username\Documents (exactly that, nothing else and nothing missing), then that part is fine. I think that's what you're saying, but I want to make sure.
Your dxdiag doesn't list any Sims 4-related errors, which could be because they're crowded out by other errors, but it's also possible that this issue isn't creating any errors at all. That, in turn, could be due to an antivirus blocking the game. So please make sure yours isn't interfering with Sims 4. And double-check what you're running—it's possible your laptop came with an AV pre-installed that you're not aware of, and that you might not want to use at all.
If you see any recent actions involving Sims 4, set the appropriate exceptions/exclusions. You can also disable or remove a third-party antivirus and use only Windows Defender, either as a test or permanently.
If that's not the issue, please look for new errors in the Reliability Monitor. Click Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day. Today is on the right.
Look for an error that happened at exactly the time of your most recent attempt to open Sims 4. If you find one, double-click it to see more details, then copy that info and paste it into a reply here. If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.
