Web Installer freezes on "waiting for 127.0.0.1" (Nvidia Open Drivers / RTX 5090) & Firefox immediate crash on launch

[koloved]

Describe the bug

When attempting to install Bazzite using the recommended Web-based ISO image (bazzite-nvidia-open:stable), selecting the "Install to hard drive" option results in an infinite loading screen/hang with the message waiting for 127.0.0.1. The web-based installer backend/frontend communication appears to fail completely.

Right before this hang occurs, the installer displays a prompt warning that a Windows BitLocker partition has been detected on the system, stating that it might interrupt the installation process. Clicking "Yes, I'm aware, continue" triggers the infinite waiting for 127.0.0.1 loop.

This issue is persistent and has been reported by other community members since at least February (similar case documented in Discord: https://discord.com/channels/1072614816579063828/1074422586894712912/1471860376302780579).

Additionally, inside the Live ISO environment, attempting to launch Firefox results in an immediate crash right after opening.

What did you expect to happen?

What did you expect to happen?

The Web-based installer should successfully initialize the local loopback server connection after dismissing the BitLocker warning, open the GUI layout, and allow the user to proceed with the OS installation.

Firefox should launch successfully in the Live environment without crashing.

i will add later when start Bazzite again

Hardware

CPU: Intel Core i5-14600K

GPU 1: Intel Raptor Lake-S GT1 [UHD Graphics 770]

GPU 2: NVIDIA GeForce RTX 5090 (GB202)

RAM: 126 GB

Storage Configuration:

sda: 3.6T

sdb: 115.5G (Live USB)

nvme1n1: 931.5G (Target drive for Linux)

nvme0n1: 3.7T (Windows drive with BitLocker enabled)

Extra information or context

Image Build: 44.20260515
Image Name: bazzite-nvidia-open:stable

Urgency Note: The Bazzite website currently states: "The Legacy installer will be phased out soon, using the regular installer is recommended." Because the regular (web-based) installer is completely broken phasing out the Legacy Anaconda installer will leave some users completely unable to install Bazzite. This makes fixing the web-installer loopback bug a high-priority issue.
Additional Info: The system has a multi-drive configuration where one of the secondary drives (nvme0n1) contains a Windows installation encrypted with BitLocker. The target drive for Bazzite (nvme1n1) is completely separate and unencrypted, meaning BitLocker shouldn't block the installation, yet the web-installer environment crashes or freezes immediately after scanning the storage layout and throwing the BitLocker warning.

Update: Legacy Installer also fails to install the payload

Attempting to use the Legacy Installer as a workaround also fails near the end of the installation process. The installer crashes with a fatal error during the payload deployment phase.

Error Message:
The command 'ostree container image deploy --sysroot=/mnt/sysimage --image=/run/install/repo/bazzite-nvidia-open-stable --transport=oci --no-signature-verification' exited with the code 1.

Important Context Regarding Storage & BitLocker:

• The system has a 4TB NVMe drive (nvme0n1) encrypted via Windows BitLocker. Decrypting a drive of this size is not a viable option for the user due to the time it would take.
• Bazzite is being installed on a completely separate, unencrypted 1TB NVMe drive (nvme1n1).
• Even though the target installation drive is completely clean and unrelated to the BitLocker-encrypted Windows drive, both the Regular (Web) and Legacy installers fail. Although both installer failures occur after the storage scan detects a BitLocker-encrypted Windows drive, I currently do not have sufficient logs to confirm whether BitLocker is the root cause. The issue may instead be related to the Live environment itself, as Firefox also crashes immediately after launch.

I was able to install the system by overwriting the flash drive, and for some reason it worked.
