Same issue after upgrading 15.5.6 to 15.5.7. Also, my 15.5.6 VMware Workstation started instantly on my NVMe, 64GB Win 10 Pro machine. 15.5.7 takes several seconds to start up. Feels like I time-warped back to spinning disks on my 10 year old computer.
15.5.7 seems to be lagging in the performance department. Thought I was the only one experiencing this.
Rolling back to 15.5.6.
