Aabed, TR still didn't work (for almost a year or even more).
Now: KP 21.22.7.466(c), Win 11 24H2 latest, Win 10 22H2 latest
1) TR > Safe mode > Delete embedded key > Reset > Reset only > Reboot > "I have an activation code" > Paste code > "You can't use trial"
2) TR > Safe mode > Reset > Reset with activation > Reboot > "You can't use trial"
3) TR > Safe mode > Delete embedded key > Reset > Reset only > Reboot > Uninstall KP > Install old offline version without checking updates > Activate > Paste code > Success > ~1-2 hours (or autoupdate) > "Your trial expired"
4..5..6+) any combination fails
