Very high memory consumption by LrC since installation on my brand new Mac

Hi, I can see a anormaly high memory consumption by LrC since installation on my brand new MacBook pro  M3 32go ram, Sonoma 14.3.1.

LrC uses RAM and virtual memory until it says “Lightroom Classic is not responding”.

However, I limited the memory cache to 10GB and the video cache to 10GB as well. The phenomenon happens even if I don't work on LrC : it just needs to be launched. I see a usage of more than 60GB memory which is considerable.

LR, PS and other software are ok. The issue concerns only LrC.

I then have to restart the software which is not practical but it works.

In general, I can work less than one hour befor the problem occurs.

The bug occurs in each work cession.

On my privious MacBook pro Intel 2027, LrC was working smoothly (2 weeks ago...)

Anyone have an idea for a solution? THANKS!
