Some extra info…
I stripped my whole (new) Rpi4 system from everything, leaving only the netamo binding with the API, Indoor and outdoor module (things) added.
With only Netamo binding installed (and the standard UI´s), I can reproduce the issue adding either Google TTS, Habmin or Rest Docs.
To eliminate (or verify) the netamo binding beeing the cause. I uninstalled the netamo things and binding.
Then I added the Expire binding (cause it was affected a as well by the issue).
After that I added Google TTS again… The issue is still there… Which leaves out the netamo binding beeing the cause. Uninstalled Google TTS again.
I then shut down OH, cleared cache (which I have done many times during the whole troubleshooting process).
Went into openhabian-config and deselected the serial ports setting, (cause I had enabled them at frist startup).
Rebooted the system.
When it was ready, I went into PaperUI igen, making sure I only had the Expire binding installed, (and the standard UI´s).
Added Google TTS - Issue is still there (expire shut down, and return back within a few seconds). Uninstalled Google TTS again.
Added Rest Docs - Issue still there (expire shut down, and return back within a few seconds). Uninstalled Rest Docs again.
Added Habmin - Issue still there (expire shut down, and return back within a few seconds). Uninstalled Habmin again.

openHAB 2.5.0-1 (Release Build)
Have in mind - This issue I first noticed on my main Openhab system which is running Rpi3B+ and OH 2.5 Stable release (upgaded from 2.5M2).
And now I´m able to reproduce the issue on a new setup using a Rpi4B (4GB Ram). (all apt updated, Rpi firmware updated as well on the Rpi4).
Both systems are running with a SSD connected to the USB port.
I have NOT tried with the SD card only.
This should be enough info for someone else to try reproduce the issue.
