can not reproduce on nvim nightly, Win 10. There is the appropriate check, so not sure why its failing for you. https://github.com/kevinhwang91/nvim-ufo/blob/752b026725a6da7d03588b004acf86b45c5526dc/lua/ufo/decorator.lua#L179

I still have this problem.

even when I use

local bufnr = vim.api.nvim_get_current_buf()
require('ufo').setFoldVirtTextHandler(bufnr, lua_ts_handler)

Use a mini config and solve it yourself. I guess your Lua ENV has been hacked.

I found the problem. Next line in my init.vim causes it
