100% CPU with nothing open.

Hi Folks,

Is there a new bug that makes the CPU go to 100% at idle? (After closing whatever I'm working on) This has only recently started happening.

The only way to fix this is to close and reopen F360, which usually hangs the program and requires a force quit. But then it happens again shortly after reopening. I've ran antivirus etc but this machine pretty much only has F360 on it.

I've attached a screenshot of Task manager.

Also, Is there anyway I can send a log file while F360 is open to help diagnose?

Cheers,

Hi, sorry about the delay. I've been waiting for the error to happen again before exporting a diag log in the hopes that it'll capture the error as it's happening. I now have it.

Just a quick question first though, does it contain private/personal information in it? If so, can i email it to a dev instead of posting it here the public forums?

Hi @MatthewNZ

Would you be able to send the log files to (Sujay<dot>dsouza<at>autodesk<dot>com)?
