On November 22, 2021, Microsoft released updates for Windows 10 and Windows 11 which, as a side effect, caused an incompatibility with different types of UDF formatted recording media.
This includes media with the ARRI UDF file system. The following products are affected:

ALEXA Mini LF with Codex Compact Drives
ALEXA Mini with CFast 2.0 cards
AMIRA with CFast 2.0 cards

Microsoft now released a new update which resolve the issue. If the update is not automatically installed, please ensure that your system is updated to:
• Windows 10: 2022-06 Cumulative Update KB5014666
• Windows 11: 2022-06 Cumulative Update KB5014668
