Just to say that you are treading on a 'grey area' with this post and one that typically we would not be able to offer advice on the community.
As you are aware, the use of emulators and retro gaming is completely legal, but the sourcing of ROMS and bios files are typically not so straight forward.
I cannot offer any useful advice in this subject. Have you tried just waiting.
Just to say that there is a large online community in other forums such as reddit that might give you the answers you need to get retro gaming up and running. I did go through this process with my steam deck a couple of years ago.
I suspect the downloading of these ROM files and the servers being used are not able to provide the download status you require or are being blocked by the android system at the higher level.
Sorry I can't be of any more help.
