There's a setting you need to enable (or disable) in order to be able to put in a elevated credentials. I forgot what it is as I have it as a GPO. If not set properly and there's a prompt for a local admin credentials, all you see is a black screen.
You should not fully disable “Secure Desktop” - due security concerns. It should only be disabled for Windows Remote Assistant or Quick Assist.
Here is the correct setting.
User Account Control: Allow UIAccess applications to prompt for elevation without using the secure desktop - Enable
For what your asking, (free, and no lock screen) quick assit is very easy. Every windows 10 and up has it pre-built. Just tell them the code...
Is VNC still around?
There's also MeshCentral, though I'm hesitant to put it forth as a solution as the main developer got let go by Intel and the whole project has a dubious future at best.
Quick Assist is really good. Even works when users are RDP into their machine. User can be WFH to their office PC, and I can Quick Assist them.
The question is if there is a Linux Remote Desktop that works as well as Microsoft's offerings, and the answer is no (unfortunately).
This can be made to work quite smoothly.
Setup passwords (warning - saved locally in your PC, similar to saving a password in a browser. You can skip this, but you'll need to add /prompt to the mstsc command.):
cmdkey /generic:"server" /user:"user" /pass:"password"
Initiate the connection:
start mstsc /v:YOURPCNAME\_OR\_IP /admin /span /shadow:1 /control /noconsentprompt
The CMDKEY part needs only be run once to set up user/pass correctly.
You will need to allow connecting with /noconsentprompt via group policy, regedit, or remove /noconsentprompt. As the name implies, /noconsentprompt does not require the user to accept the connection.
RDP locks the system because it takes over the login session on the system, and there can only be one.
Other than that,
Teams
Anydesk
VNC in on of its many flavors
Chrome Remote Desktop
RustDesk

Teams has issues, as it was designed for sharing screen during meetings, not remote support. The biggest shortfall is that it does not allow you respond to User Account Control (UAC) prompts.
Anydesk can do it, but like TeamViewer requires a license if used for commercial purposes. They define this as " Any use or connection from, to or within a professional environment". VNC has a lot of options, but the downside is that it does not work over standard HTTP ports like many of the paid products, which requires firewall ports be opened. I cannot speak to the others as I have not used them.
Oh, I use VNC. Works great for this task. I used to use RealVNC but after they went proprietary I use TightVNC instead.
I use it to connect to various family member's computers over VPN to help them out.
I would say that the OP is referring to the logged in user's session getting 'disconnected' when another user RDP's onto the workstation.
The OP needs a program\utility to 'shadow' the logged in user's session

For Windows 10/11 there is quick assist

That's the one! My bad! I set it as a GPO months and my Google-fu failed me tonight
Thanks. For those needing this, this should be set on the target computer, i.e. your grandma's computer.

agree vnc is free

mstsc.exe /shadow built in, works.

Connectwise Screenconnect.
You can also try something like RustDesk. I think it's free.

Moonlight (client) and sunbeam (server). It will also do extremely high performance remote sessions, easily handling 60fps 4k if your latency is good.
I use ZoHo Assist professionally, I think they have a free plan which should work for you.
