I/O OS error in python programs

According to another thread about that error, it's possible it happens when you have an ad blocker running.

If turning off ad blockers does not fix it, I recommend using "Report a problem" in the upper right to submit a support request.

turned my adblocker off, still has the same error.

Since turning off ad blockers does not fix it, did you submit a support request to KA support staff?

I did that first, in fact, before going here.
