Black screen when selecting file on Meta Quest 2 #55

While creating a VR application for the Meta Quest 2 (Android), I tried to implement the file browser to select a txt file and read the contents at runtime. This all works great, apart from the fact that I am getting a black screen when selecting the file. Nothing breaks, as I can press the Quest button to get back into the game and the file is correctly read. Is there any way to fix this? I would like it to be seamless without the black screen and having to press the Quest button.
