Description of Issue

I have been using LG laptop as a roon core for about an year without any trouble.
All out of sudden, Roon on the laptop kept on closing down by itself after 20 mins of operation.

I didnt touch anything on my laptop(Windows update disabled) and network.

Having been troubled about a month, I have updated Windows and replaced router. Same issue.

Recently, I reinstalled Windows 11 Pro to see whether it fixes the bug, but the same issue happens.

Can any specialist help? Since the Roon Arc was available, all my playlists are updated on Roon only combining musics from my source, Tidal and Qobuz.

Living without Roon has become a hell…
