So I've been working on several LWCs for SF community and suddenly the modules/c folder in browser's DevTools (both Firefox & Chrome) which contained all the custom components present on page dissapeared (Note: I'm working in sandbox). What I already tried:

  • toggling Lightning debug mode for current user;
  • toggling Lightning Web security in Session setting;
  • clearing browser cache;
  • changing component's API version

but I didn't succeed with any of them.

The only way to debug scripts live for me now is to explicitly put debugger statement as a breakpoint where needed. Strangely, 2 weeks or so ago everything was fine, and even another Sandbox org from a different project doesn't have this issue. Has anyone encountered the same issue before?Here's how my Sources tab in DevTools lool like
