Another thread about a maxed out CPU

[josh.rickun]

Hi everybody. Fusion is consistently running the CPU up to between 100-200% and fans blaring, doesn't matter if a document is open or not. I've installed 3D Connexion (a previous solution), cleared the cache, uninstalled Fusion and reinstalled, restarted my computer; all with no luck. I recently upgraded my OS to Big Sur, but the problem didn't start until a few days later. Any suggestions? Here is the diagnostic log.
