Lock screen to Login Screen delay issue

I have a issue where there is a huge delay between lock screen (the screen where you have a background and time) and login screen (the screen with an account picture and dialog box to input the password).
I tap/press any key/click on the lock screen and it takes so much time to load the login screen, sometimes the lock screen reappears after 10-15 seconds or so before i can tap again to try to go to the login screen.
I've tried the following to fix the issue-
- Disabled widows spotlight
- Disabled lock screen
- Performed Clean Boot
- Tried Safe Mode
- Turned off startup services

My Windows 10 version is 1903 and is dully updated as of the time of publishing this post. I have pin set up to login.

It's definitely not because of the old or slow hardware because
1.) on a much older hardware the startup might be slow but this problem doesn't exist.
2.) After once i login successfully and lock the computer (start+L), the issue's still there. That is about 30 seconds waiting time between lock screen and login screen.

I'm really looking forward to all your solutions.

I can clean install windows but don't want to. Lots of data and nowhere to backup. Also lot of hassle.

I wanted to there to be something else on record for the next person searching for solutions to this problem.

If this is still a problem and you've tried a million different things or if you've gone ahead and reinstalled/reimaged, etc. and the issue seems to persist, I wanted to add something for the next person doing an exhaustive search for a remedy to this problem to try:

This is on a Windows 10 Home machine that was upgraded from Windows 8, but it may be applicable more - I was getting an unreasonable delay from my lock screen to the password screen. I searched and searched and searched and tried almost everything I saw, so I resigned myself to take a few wild swings before I formatted and reinstalled. There are suggested solutions of clean boot, system reset, editing the group policies, registry hacks, editing maintenance tasks, you-name-it, but something I never saw suggested was opening the system configuration editor (msconfig.exe) and under the "Boot" tab, changing the "Timeout" to 3 seconds (mine was set unreasonably at 30 seconds). I'm not sure if this was a leftover setting from Windows 8 or something sneaked in with malware or an update, but this solved my delay problem.

I hope I can save someone else from a wipe and reinstall.

Thank you SO MUCH!
I've been searching for a solution on Google for days before I find your post on 3rd or 4th page of search results. That was it.

So, for any people that may have the same problem in the future, let me add some keywords and keyphrases to this topic :

Windows Login form takes a long time to appear

Windows Login form takes too long to appear

Windows login screen delay fix

Windows login screen stuck on background image

I may need to start a new one but thought I'd try here first
1. was this ever solved?
2. on a 20H2 Win 10 Home system, with an SSD - HP Pavilion 15 - every boot/restart the User Profile load is delayed what seems like 3 times - you get the initial display painted as the system is fully restarted/booted, a quck "spin" of the Windows 10 swirling balls, then a blank or "fuzzy" lock screen image [depending on how I set the lock screen - effort to avoid or debug the problem] with about a 9 second delay, hit a key to get it to go to the password input , get another 9 second delay, and FINALLY get to the input field.
3. The simplest verdict is "the core default profile is corrupted". I say this because setting up a brand new User the behaviour is almost identical to the "old" user account. This is without a network login [i.e. we're not using the microsoft account to login, just a local account with a plain password/login].

I ran a completed DISM / Restore routine. Also ran chkdsk just for fun....
The system otherwise runs spectacularly well - absent the delays the boot time is about 10 seconds.

I may try to copy a default profile from elsewhere and setup again but am doubtful that anything other than a clean install will help this.

any suggestions would be most welcome
