No idea what is going on... One minute an api path works, the next i'm unauthorised...

### Expected Behavior

maintaining session and not getting access denied 401

### Actual Behavior

So the web application is 90% built and has been fine for months, but now all of a sudden I lose authentication and session on a once working and untouched api route. If I rename the api route to abc it works again but if I rename it back, it doesn't work again...

Tested this in browser and postman and was fine in both...

http://127.0.0.1/api/advocate/cases (access denied)
http://127.0.0.1/api/advocateeeee/cases (works)
http://127.0.0.1/api/advisors/cases (works - same class and method different route)

I can't supply export as the project is under NDA and has sensitive material.

Uninstalled, went to appData folder, removed all the left behind stuff (nice un-install guys!) and then re-installed. Re-imported exported data and all is working again...

### Reproduction Steps

NDA can't share files.

Start by retrying the listed API paths in a browser or Postman and compare the failing /api/advocate/cases route with /api/advocateeeee/cases and /api/advisors/cases. The issue provides no project files, tests, or shareable reproduction; the work is done only when the authentication and session behavior can be reproduced and the route-specific cause is identified.
