Hi,
Forget ChatGPT as "BubbleUPnP Server" has nothing to do with this.
I suppose the Android Media Store (the system component that indexes music files on local storage) went kaboom with what is stored on your SD Card.
There is unfortunately no way to force the Android Media Store to rescan files. It is supposed to do it on reboots so you may want to try that with your SD Card inserted
and wait for a while.
Other than that, you can still access your SD Card, browsing by filesystem (thus not using the Android Media Store) this way:
- go into the Library tab
- enter the folder whose title is "Folders"
- use the + floating button at the bottom right
- use the system file picker to select the root folder of your music stored on the SD Card (repeat if you have several root folders)
=> Now you can browse this folder in BubbleUPnP
