Check if your init.vim has something like this:

let g:indentLine_concealcursor = 0

Earlier NeoVim versions used to ignore this but now this is an issue since error is being reported. Correct should be having a string with characters only comprising of 'i, n, c and v'

I'm facing the same issue with vim 9.0 homebrew build.

Error message:

Error detected while processing BufWinEnter Autocommands for "*"..function <SNR>80_Setup[6]..<SNR>80_IndentLinesEnable[10]..<SNR>80_SetConcealOption:

I tried removing indentLine configs based on vim/vim#10128 (comment) but that doesn't seem to help. The only fix is removing indentLine completely.

My .vimrc config for reference: https://github.com/AravindVasudev/dotfiles/blob/main/vimrc

Thanks. Changing

let g:indentLine_concealcursor = 0

to

let g:indentLine_concealcursor = ""

in ~/.vimrc fixed it for me
