Game keeps crashing

cll1275​  As a test, please try playing in a clean user folder.  Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop.  When you launch the game, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you've moved but temporarily unread by the game.)  Don't add anything to the new folder yet; just start a new save and see how it runs.

If you get another crash, please provide a dxdiag.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.

Leave the Gallery issue aside for now.  I'd like to know whether the game crashes or freezes independently of that.  Once it's running properly again, we can try to fix the Gallery, if it's still a problem.

Sorry for the late reply i didnt have time to try ot out but i tried it and it is working again the gallery still is kinda glitchy but it has grotten better

cll1275​  Are you seeing any issues when not using the Gallery?  And what happens now when you try to use it?

When i try to save stuff to my library from the gallery it often freezes up.... just placing it goes well but as soon as i try to save it it goes wrong

cll1275​  Is Sims 4 reading a folder inside the OneDrive folder?  Here's how to check:

If it is, try pausing OneDrive syncing.  You can do this by right-clicking the cloud icon in the lower-right corner of the screen, or perhaps hidden in the Tray (^ icon).

If that doesn't help or isn't relevant, does your computer support wifi?  I'm wondering whether the connection is the issue.  If you do have wifi, please try a different network if possible, for example your phone set as a mobile hotspot, using data rather than your home wifi.
