Cannot access './templates': Input/output error

Bug description:
A folder in my repository, “templates” has become unreadable and causes my Python program to stop working.

Expected vs Current Behavior:
This was working up until very recently. The templates folder serves a single .html file with Flask. Now the program throws an exception as it can not access this folder. The folder also shows as “open templates: input/output error” in the Replit file browser.

Steps to reproduce:
Open console

cd templates
bash: cd: templates: Input/output error
