I don’t think this is a normal behaviour.
Rebooting might always help.
It may be useful to check if the container is shown as started in waydroid status. If not, try devel-su waydroid container start and check if it succeeds. If there will be an error, the full version is probably in waydroid logs.
This might also help, even though it is marked as fixed (this helped me too. You might want to check my issue as well). I don’t remember what exact line the issue talks about, but if you will open the config file I am sure you will find it.
In general, when installing Waydroid I tried every possible solution I found in waydroid repository issues, Reddit, SailfishOS waydroid repository issues and everything else I could find, even if it was marked as fixed and not required or not directly related to my problem and logs. I am not really an expert at waydroid but that’s what I did to get it to work.
