Can't log in on Kubuntu 26.04 - Something went wrong. [4kv4v]

I installed the intune-portal on Kubuntu 26.04 successfully:

Package: intune-portal
Version: 1.2603.37-resolute

and the app starts well, but after signing in using SSO, I see an error:

Something went wrong. [4kv4v]

Here is a screenshot:

And here is logs when I run it in console:

I use KDE desktop environment on Wayland (installed freshly from the Kubuntu ISO), all of the settings are default.

Rebooting, purging, reinstalling - nothing helps.

Please share more details on how to debug this issue and find the root cause.

No source files or tests are mentioned; start by reproducing the SSO flow through the intune-portal entry point on Kubuntu 26.04 with KDE Wayland. Inspect the provided OneAuth/MSAL console output around error code 1001 and [4kv4v]. Done means identifying a reproducible root cause and documenting a fix or actionable next diagnostic step.
