Reproducible: Always

Steps to Reproduce:
1. Install F43 beta, update
2. Install waydroid
3. Configure according to install instructions https://docs.waydro.id/usage/install-on-desktops
Actual Results:
Nothing starts

Expected Results:
We can use waydroid :)

Additional Information:
Likely something to do with the required Python rebuild. Filed this bug to be certain.

Comment 1 Jonathan Steffan 2025-09-28 15:26:18 UTC
The Python mass rebuild is complete. On a VM with all pending updates applied, this issue still persists.
