I’ve never seen this error before. It occurs on some of my systems with patch MS20-APR: Servicing Stack Update for Windows 10 Version 1909 - Windows 10 Version 1909 - KB4552152. I’ve searched online and this error code doesn’t come up anywhere. Any ideas?
You’ll probably need to convert that signed integer value into an unsigned hexadecimal to find Google results. Check Critical Sep-19 Patches servicing stack & Monthly failed with exit code:- -2146885628 for some notes on how to do that.
