Permanent reloading page in "nextcloudpi panel" since V1.55.4 and missing WiFi since v1.55.0 on RPI5

PROBLEMS

After updating Nextcloudpi on RPI5 8Go with Debian moved to Armbian since 1.55.0 : I noticed two strange behaviors:

-1- Armbian version 25.2.3 removed WiFi hardware on RPI 5 ?!?!?! --> impossible to find the device
: wrong firmware bcm80211 ? --> I've downloaded old image file (v1.54.0) and tested with same RPI5: WiFi is present on RPI5 running on Debian 11 !?!?!? (instead of Armbian)

After investigations: I've noticed the WiFi lost since version 1.55.0 on RPI5 probably due to Debian migrated to Armbian : this last OS seems not fully supported on RPI5 with operational WiFi because I've tested the last version NextcloudPi 1.55.4 on RPI4 4Go which keep Debian OS : its WiFi works perfectly ! Please make an investigation about it or replace armbian by debian OS for RPI5...

-2- NextcloudPi panel V 1.55.4: after reloading page or clicking different functionality from left side menu, ~20secs the panel display a blank page with message "Something went wrong. Try refreshing the page". Despite refreshing same page, the blank page still back after few seconds with same message... This issue appeared after updating from 1.54.0 to 1.55.4. --> I've tested same version on RPI4 Debian OS and v 1.55.4: works fine and stable.

See video example: https://youtu.be/dDv5FH03gjA

I think that bug is linked with Armbian OS running on RPI5... because the big difference between RPI4 (stable system and operational WiFi) and RPI5 (unstable system and missing WiFi) is the used OS... Debian (RPI4) is more reliable than Armbian (RPI5)... and RPI4 + Debian OS seems more faster than RPI5 + Armbian OS.

No source files, tests, or entry points are identified. Start by reproducing both the missing WiFi and panel reload failures on Raspberry Pi 5 with Armbian 25.2.3, then compare against Raspberry Pi 4 with Debian and the 1.54.0 image. Done means the responsible regression is isolated and a targeted fix or documented support decision is established.
