Has degraded battery has anything to do with this?
Cant access the apps that uses face id feature. Instead of showing the passcode its shows “try again”. I cant even open my photos app😭😭

Yes – Face ID requires a healthy battery to meet the computational demands involved in recognising your face. What's the Maximum Capacity % here?...

"Any ideas how i can fix this?"
Apple suggests having the battery replaced at around 80% Maximum Capacity – so have the likely weak, aging battery replaced to restore Face ID:

Welcome and thank you for reaching out. 🤗
Follow these steps, testing after each step:
If that didn’t work, then it could be a hardware issue.
Using diagnostics available in iOS 14.6 or later, Apple has detected an issue with your TrueDepth camera that might cause it to not function as expected. The TrueDepth camera contains lasers, which might be disabled for safety reasons if the device malfunctions or is damaged. This won't prevent you from using your iPhone or iPad, but until your iPhone or iPad is updated or serviced, you might not be able to use Face ID, Animoji, Memoji, and some other features that use the front camera.
As a result, I recommend service.

Let me make sure I understand you correctly. Instead of admitting that there’s a feature that worked well in ios26 and is now causing problems in ios27 and fixing it, you’re actually telling people to go and buy a new battery for their phone at their own cost???

My battery health is excellent and I’ve downloaded iOs27. That’s when I lost ALL FACIAL RECOGNITION. IT IS NOT A COMPONENT problem.
