Safe Mode loads Windows with the minimum drivers it needs - and a PC that boots there has a healthy core. Use that opening to remove the update from inside Windows itself.
There is a useful diagnosis hidden in Safe Mode: if Windows starts there, the hardware and the core system are fine, and whatever the update broke lives in the parts Safe Mode skips. Better still, Safe Mode gives you the normal desktop tools - Settings and the Control Panel - so you can uninstall the update the ordinary way instead of through recovery menus. This route rescued many of the slow, frozen systems reported after KB5094127.

If Settings is too slow or half-frozen even in Safe Mode, an admin Command Prompt is faster. The Windows Update Standalone Installer can remove a KB directly:
wusa /uninstall /kb:5094127 /quiet /norestart - replace the number with your update's KB.Honest limit: a few cumulative updates refuse the wusa route because of how their servicing is packaged. If wusa reports the update cannot be removed this way, use the Settings list or the WinRE Uninstall Updates button - both attack the same package through the servicing stack instead.
While you are in a working desktop - even Safe Mode with Networking - set the trap for the update's return. In Settings → Windows Update, click Pause updates for 7 days. Without this step there is a real chance Windows Update downloads and reinstalls the same cumulative package during your next normal session, and tomorrow morning looks exactly like this morning.
A PC that cannot boot even in Safe Mode after an update has a deeper problem - the damage sits in files Safe Mode also needs. That rules out the gentle routes and points you at the recovery-level fixes: the WinRE quality-update uninstall, System Restore to the pre-update point, or DISM package removal from the WinRE Command Prompt. And if all of those fail while the disk is also making noises or vanishing, stop repairing Windows and check the disk itself.

Sort the Uninstall updates list by install date and remove the newest cumulative or security update - the one installed the day the trouble started. The video series core guide shows how to identify it by date even when the KB number means nothing to you.
It should not - Safe Mode is a one-boot choice from Startup Settings, not a permanent mode. If the PC keeps returning to Safe Mode, check msconfig - the Safe boot checkbox on the Boot tab may have been set permanently at some point; untick it.
