[hadyelzayady]

the issue is due to setting foldmethod="manual" exactly this trace from top to bottom

diffview.nvim/lua/diffview/scene/views/file_history/file_history_view.lua

Line 113 in 4516612

win:use_winopts({ foldmethod = "manual" })

diffview.nvim/lua/diffview/scene/window.lua

Line 309 in 4516612

self.file.winopts[option] = v

diffview.nvim/lua/diffview/utils.lua

Line 383 in 4516612

vim.opt_local[option] = value

which hangs when foldmethod="manual"

I commented it in my code untill I have time to solve it
