I've donwloaded beta-version 2567 and my computer hangs during optimalisations. I have a PC with Ryzen AMD Ryzen 9 3900X with 32GB Ram.
It executes 24 passes (24 cores in the CPU) and then nothing moves anymore. I had to do a hard reset.
After the restart I could do the next 24 passes to finish the optimalisations.
Since several months I've noticed the problems with memory management during optimalisations and that problem is still not solved.
