[3.1.0] Account signs out when opening a model — cannot log back in (Bad Request / Unknown error)

D5 Render Version: 3.1.0

Account: estudiocientounomx@gmail.com

OS: Windows

Issue Description:

After updating to 3.1, my account signs out as soon as I open a model. The launcher shows me as logged in, but the moment the render engine loads the project, the account is dropped. From inside D5 I cannot log back in at all:

•	Email + password → red banner: “Bad Request”

•	Log in with Google → red banner: “Unknown error”

Both methods fail every time. Screenshots attached.

Already tried (no change):
• Full uninstall + manually deleted %APPDATA%\D5Render, %LOCALAPPDATA%\D5Render and temp folders, then clean reinstall
• Running D5 as administrator (and also without admin)
• Opening the project from inside D5 instead of double-clicking the file
This looks like the same problem reported here: Cant log in with 3.1 — where you mentioned you had received similar reports and started investigating.

Log file attached (generated with Collect Logs).

Request: Could you please send me the download link for 3.0.1? I have active client projects and need to keep working while this is investigated. I’ll install it in a separate path.

Thanks in advance.
