Indeed, that is my experience also.
For me, the issue was already present on Android 14 for quite a while.
Initially I also rebooted to clear the issue, after that I learned that just putting it in the lockscreen twice and unlocking it again after a few seconds gave me access to the USB drive after reinserting it again.
For me it is not an issue, I just leave it at "charging only when unlocked" and I wouldn't mind if people initially focus on the Android 15 release instead, I think the developers are already busy enough as it is, but I cannot speak for others, I am not sure how pressing the issue is for them.
Also, this is absolutely not a complaint; the work is done for free, (although, giving donations to the GrapheneOS project is totally recommended) therefore I am really greatful for the fact we have such a fantastic Android-based secure operating system, I cannot stress that enough.
