os-prober failed at a point it's scanning /dev/sda2

Anyone experienced on:

os-prober failing, is hanging at a point it's scanning /dev/sda2
i.e. partiion of ESP, so will grub-mkconfig with enable OS probe option

$ os-prober
/dev/sda12:MX 19.4 patito feo (19.4 ):MX:linux
/dev/sda2@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi

What should repair this (hunch a imperfection in ESP) ?

Fact is it's not necessarily stuck at the ESP as it'd be the next/other partition as hinted by bash trace some lines before to the hang point:

(is hanging here)

Any bright idea to get to the correct solution?

Re: os-prober failed at a point it's scanning /dev/sda2

/usr/lib/os-probes/50mounted-tests is yet another script you mght want to trace.

cat /etc/fstab
lsblk -f

And please use [code][/code] tags.
