Paste anything into nvim from windows clipboard

What keys exactly did you use? Is it the system paste, i.e. ctrl-shift-v or ctrl-v ?

Right click -> Pasting

Ctrl+shift+v paste works fine. In 0.6.1 right click paste works.

Does pressing "+gP crash?

Does pressing "+gP crash?

Yes

Also it's not crashing, it just freezes for a good ~1 minute, and then does not paste the output. I checked if it was anything in my init.vim, but it occurs even with an empty file.

Are you using Window Terminal and xclip?
maybe this relates: microsoft/terminal#11945

I had the same issues before, terminal randomly freezes when pasting from windows to WSL2
I tried to remove xclip and have xsel installed for the last week. I have not experienced this problem.

I reproduced this in NVIM v0.8.4-dev-2+gb1ae775de and can confirm that installing xsel seemed to have resolved the issue. I don't have xclip, but I also use win23yank.exe per recommend at https://github.com/neovim/neovim/wiki/FAQ#how-to-use-the-windows-clipboard-from-wsl.

Could you try the suggestion given by :help clipboard-wsl ? If that works, I'll update the FAQ to point to that instead. https://neovim.io/doc/user/provider.html#clipboard-wsl

Yep, it works, but it's very slow. Doesn't seem like a good solution. Having win32yank.exe in the path plus installing xsel "just works". No configuration, and it's fast.

By the way, I had to convert the suggestion to Lua before adding to my config. Let me know if I messed anything up in the process.

vim.g.clipboard = {
  name = 'WslClipboard',
  copy = {
    ['+'] = 'clip.exe',
    ['*'] = 'clip.exe',
  },
  paste = {
    ['+'] = 'powershell.exe -c [Console]::Out.Write($(Get-Clipboard -Raw).tostring().replace("`r", ""))',
    ['*'] = 'powershell.exe -c [Console]::Out.Write($(Get-Clipboard -Raw).tostring().replace("`r", ""))',
  },
  cache_enabled = 0,
}

Does win32yank.exe and xsel still works for now?

I can confirm the h: clipboard-wsl work well, but is slow just when paste using right click or p not if using Ctrl-Shift-v.
Ctrl-Shift-v seem still faster and yanked (y) also still faster.

vim.g.clipboard = {
  name = 'WslClipboard',
  copy = {
    ['+'] = 'clip.exe',
    ['*'] = 'clip.exe',
  },
  paste = {
    ['+'] = 'powershell.exe -c [Console]::Out.Write($(Get-Clipboard -Raw).tostring().replace("`r", ""))',
    ['*'] = 'powershell.exe -c [Console]::Out.Write($(Get-Clipboard -Raw).tostring().replace("`r", ""))',
  },
  cache_enabled = 0,
}

But again, need to add above configuration to work.
Even with that configuration sometimes :%y+ is not work, and i still cannot get the root cause.
