Message can not be decoded

### Steps to reproduce

I have a Message in a chat, which can not be decoded.
But the same Message is already successfully decoded on my Mobile Device (same user account).

### Outcome

The feature for getting the decryption-Key from "other devices" doesn't work.

The same issue on two PCs (Laptop Win 11 / PC with Win10)

### Operating system

Windows

### Application version

Version von Element: 1.11.32 Version von Olm: 3.2.14

### How did you install the app?

_No response_

### Homeserver

### Will you send logs?

Yes

No source file, test, or entry point is identified. Start by reproducing the undecryptable chat message on Windows and collecting the promised logs, then compare the desktop behavior with the successful mobile decryption; done means the decryption key can be obtained from another device and the message can be read.
