How to restore the working state of the smartphone when "Unfortunately, System UI has stopped."?

Question

Android

After updating the smartphone to "cm-12.1-20150518-NIGHTLY-evita", the inscription "Unfortunately, System UI has stopped" began to appear on boot, with the ability to click "OK". After clicking (on OK), the inscription appears again, and so on ad infinitum. At the same time, there is an Android Lollipop background in the background, and when you hold down the power key, you can select "Power off" and "Reboot". Nothing else can be done in the smartphone's graphical interface.
I read on the forums that in such cases it is necessary to return to the old version of CyanoGenMod.
In such cases, I tried to return (reinstall CM) to versions:
"cm-12.1-20150514-NIGHTLY-evita"
"cm-12.1-20150516-NIGHTLY-evita"
"cm-12.1-20150517-NIGHTLY-evita"
With premade "wipe davlik cache", "wipe data/factory reset" and "wipe cache partition" using ClockWorkMod 6.0.4.8.
After the reinstallation was the same inscription as before.
What else needs to be done to make the smartphone work?
PS Smartphone HTC One XL. I have been using CyanoGenMod for about 3 months.
