There is a chance that this was fixed in patch 9.0.1252 - that fixed a bug how Vim restores the MS-Windows console buffer on exit - it would impact the new windows terminal as well as the old command console.

Ah, hang on - something else I remember,
Vim does change the cursor shape - that is by design.
But, you can configure it how you like - for example in my .vimrc file;
This works on windows terminal;
augroup CursorSettings
autocmd!
" Alternative codes:
" 1 -> blinking block
" 2 -> solid block
" 3 -> blinking underscore
" 4 -> solid underscore
" 5 -> blinking vertical bar
" 6 -> solid vertical bar
autocmd VimEnter * let &t_SI.="\e[5 q" "SI = INSERT mode
autocmd VimEnter * let &t_SR.="\e[4 q" "SR = REPLACE mode
autocmd VimEnter * let &t_EI.="\e[2 q" "EI = NORMAL mode (ELSE)
autocmd VimLeave * let &t_EI.="\e[6 q" | normal i
augroup END

You can change the VimLeave line, to match your custom terminal cursor style.
autocmd VimLeave * let &t_EI.="\e[2 q" | normal i

About this bit -
NOTE: When Vim exits the shape for Normal mode will remain. The shape from before Vim started will not be restored.
I found it's possible to hook into the VimLeave auto-command, and make it switch the cursor back to the insert mode cursor at the end:
autocmd VimLeave * let &t_SI.="\e[6 q" | normal i
Maybe I've been relying on an undocumented "feature", but I found I could get it to set the insert mode cursor on exit. The | normal i bit achieves that.
I'm assuming this is still the case. I just realised that the stuff before the | may be completely redundant, I can't recall now why I did it like that. Anyway, I was able to get the insert mode cursor restored to the console again on exit.

arghh, I'm just testing all this now on latest release of Windows 11 (22H2).
It's not behaving the same anymore like it was when I first set it up on windows 10 - that was maybe two or three years ago.
So, I'm investigating further. Its all a bit strange. I'm getting underscore when I set to block, I'm getting block when I set to bar etc. It's really weird at the moment.

I haven't looked into this yet, but v9.0.0347 might be related.

Related, but OK I think.
I cleaned out my vimrc, trying to keep things simple - and it looks like it still works OK - if I just do a minimal set like this;
let &t_SI.="\e[5 q" "t_SI = Start INSERT mode
let &t_SR.="\e[4 q" "t_SR = Start REPLACE mode
let &t_EI.="\e[2 q" "t_EI = End Insert mode - usually starts NORMAL mode
let &t_te.="\e[0 q" "t_te = Termcap End - usually called when exiting Vim.
and when I just have that (without the auto-command) - it seems to work OK. The termcap end (t_te) seems to be a new trick that I didn't know about before when I first set all this up in my environment - t_te is so much cleaner than hooking into VimLeave. Also, it seems that "\e[0 q" is working now properly. That was confusing me. But, I think it's actually better the way it is now.
I suggest that the only line @clor09 needs (to achieve their initial expected outcome as written) is just this one line in the vimrc;
let &t_te.="\e[0 q"
I'm assuming @clor09 is on Win 11 release 22H2

I found the cause of my confusion. I must have moved things around in my vimrc, some time ago, and somehow had set termguicolors after setting the cursor settings.
@clor09
Note, in the vimrc file, all these cursor settings must come down after setting up the colorscheme and termguicolors (if you set them.)
