Maybe the same as #624 ?

Maybe the same as #624 ?

I think you have a point,After I commented out the relevant code, the problem disappeared along with the Nerd fonts icon.

file in :nvim\lua\modules\configs\completion\cmp.lua

[Jint-lzxy]

@Qejun d506a19 implemented a temporary workaround, you only need to pull the latest changes.

This is part of the v0.9 migration.

[Qejun]

I pulled the new config file, but didn't upgrade nvim from 0.8 to 0.9, so my problem was not solved.
I took the suggestion in https://github.com/ayamir/nvimdots/issues/624
and the solution in version 0.8 is as follows:
file in \nvim\lua\modules\configs\completion\cmp.lua

return function()
	local icons = {
		kind = require("modules.utils.icons").get("kind"),
		type = require("modules.utils.icons").get("type"),
		cmp = require("modules.utils.icons").get("cmp"),
	}
	local t = function(str)
		return vim.api.nvim_replace_termcodes(str, true, true, true)
	end

	local border = function(hl)
		return {
			{ "╭", hl },
			{ "─", hl },
			{ "╮", hl },
			{ "│", hl },
			{ "╯", hl },
			{ "─", hl },
			{ "╰", hl },
			{ "│", hl },
		}
	end

	---Handling situations where LuaSnip failed to perform any jumps
	---@param r integer @Cursor position (row) before calling LuaSnip
	---@param c integer @Cursor position (col) before calling LuaSnip
	---@param fallback function @Fallback function inherited from cmp
	local luasnip_fallback = vim.schedule_wrap(function(r, c, fallback)
		local _r, _c = unpack(vim.api.nvim_win_get_cursor(0))
		if _r == r and _c == c then
			fallback()
		end
	end)

	local cmp_window = require("cmp.utils.window")

	cmp_window.info_ = cmp_window.info
	cmp_window.info = function(self)
		local info = self:info_()
		info.scrollable = false
		return info
	end

	local compare = require("cmp.config.compare")
	compare.lsp_scores = function(entry1, entry2)
		local diff
		if entry1.completion_item.score and entry2.completion_item.score then
			diff = (entry2.completion_item.score * entry2.score) - (entry1.completion_item.score * entry1.score)
		else
			diff = entry2.score - entry1.score
		end
		return (diff < 0)
	end
