I tried the following combinations:
<C-U>exe "" . (v.count ? v:count : "") . "bprevious"<CR>
<C-U>exe "” .. (v.count ? v:count : "") .. "bprevious"<CR>
<C-U>execute "” .. (v.count ? v:count : "") .. "bprevious"<CR>
<C-U>execute "” . (v.count ? v:count : "") . "bprevious"<CR>
None of them work.
Vim has been updated to version 9.1.1435
