Latest Windows 11 security patch might be breaking SSDs

"Latest Windows 11 security patch might be breaking SSDs under heavy workloads."
May even "brick" the target SSD... see comments at the below link.

After attempting a regular periodic BU with Acronis of sys dr c:, SSD to SSD, I noticed reallly slow and erratic disk write speeds in Taskmanager>Performance>Dr W: to target SSD. What normally took about 12 min...took almost 30 min.
Turns out that Win 11 auto update 24H2 with the KB5063878 update installed without me knowing on 08-16-25.
Prompted me to Google search to above link.
Because UG was within 10 days it was deletable under System>Update (bottom of page)
After delete>restart ran same BU. Back to normal of about 12 min...with no drastic erratic disk write speeds.
Don't know if this is being addressed with a remedial UG...but just in case I have turned off auto-update in services.msc.
***update
1. Checking services.msc F***'n Windows keeps suppressing "disable" auto update to manual trigger.
2. BTW, here's the best vid I've seen on uninstalling any/all recent KB* win 11 updates using command prompt
