FP5 not booting after update to Android 15

Hello both! Yes, I think it is related to the fingerprint issue, because I reported it on the 18th of August (https://forum.fairphone.com/t/how-to-recover-photos-from-internal-memory-on-fairphone-5-stuck-at-boot-only-recovery-accessible/124394). Weeks before the problem with fingerprints and Android 15 appeared. And my phone had changed its behaviour after falling to the floor and getting the on/off button stuck. Some weeks later, I opened the phone, cleaned it with electronic cleaner, etc., but the device still stopped at the green background with the lighter green line. I think this is related to the fingerprint sensor and the Android 15 issue.

My question is: can I solve it without losing the photos? Or does anyone have experience with professional memory or mobile phone recovery services (~700€)?
