Problem with mw

[OIVJasminka]

Hi!
I have an issue with 5G-MAG ref. tool.
We have a 5G BC signal from the transmitter site, R&S transmitter and core, UHF channel 42, BW 8MHz, subcarrier spacing 1.25kHz, circular polarization AS, clean LOS. The signal strength is 73dBuV on log-perodic antenna.
In the test we use RF Blade SDR and PC with i5-10500 CPU@3.10GHzx12
We tried various combinations of module versions and the following combination proved to be the most stable:
Ubuntu 20.04
Modem 1.2.2
mw 0.9.1
Application 0.9.0

The problem consists in the following:
When restarting the modem, we first need to hide the antenna so that the CINR drops to about 1-2dB for the modem to synchronize and lock on the signal. We return the antenna to a stronger signal, the modem works stably for a few minutes and then breaks.
mw window doesn't look as it is described https://github.com/5G-MAG/Documentation-and-Architecture/wiki/Use-Case:-HLS-playback-over-5G-Broadcast and has no play button, so we can't get a video on the application. In mw version 0.9.0 the play button appeared sometimes, not every time.
ffplay is working fine, but since the modem is unstable, the video soon breaks.
Do you have any suggestions on what we could try to make the modem work stably and what to do with mw?
