BrowseNX closes after a few minutes when watching videos with the message "This screen will now close"

[muxi1]

BrowseNX closes after a few minutes when watching videos with the message "This screen will now close". The problem exists with the last version 0.4.1, as well as a self-compiled version (with libnx 4.4.2-1). I am using AMS v1.5.5 with dns_mitm and exosphere enabled under an emuMMC on FW 16.1.0. BrowseNX is run by title override to use the maximum available memory. I have already searched for solutions to the problem on the web, but nothing can be found. Any ideas? Thanks in advance.
