Logic Pro X 10.5.0 - CPU load constantly on 100%

Question

Logic Pro X 10.5.0 - CPU load constantly on 100%

I just updated to the newest Logic Pro X. After using it for a while, the CPU started to run on 100% out of the nothing with 5 threads even when Logic was idle. The project got unusable after this, even no playback possible. It's an extremely disturbing bug, which makes the software literally unusable.

I wanted to make sure that it's not some plugin which causes the issue, so I deleted ALL the tracks in the project, but the high CPU load still remained.

Even if I restart Logic, the same project is corrupted forever, however some other projects work fine.

It is definitely a serious bug, did someone experience the same, or maybe found any solution?

Mac mini, macOS 10.15

As far as I can see it´s a bug with the rewire option - see preferences/audio

I turned rewire option off and the cpu shows normal behaviour.

(Even I had some crashes the last days. The report always says something about a problem with Ableton... but I haven´t use Ableton since I use X 10.5 - but the rewire for Ableton was on like always the years before.

Now I will see what happens.

Right now it looks good.

Logic 10.5 is still buggy. Waiting for an update asap.

Exactly same problem here!

On an 10 kernel iMac Pro and a simple logic song... another much more complex song makes no problems!
