ETS Project File import failing with Unknown Error

Hi, I am running a fresh install of Home Assistant OS on Raspberry 5 (HA Core 2024.3.0), with the KNX integration installed (v 2.12.2). Trying to import my ETS6 Project file unfortunately systematically results in an "**Upload failed**" dialog box with an "**Unknown error**" message. I am happy to share my .knxproj file over private message if it can help. Other than that, happy to provide log files or to perform any steps that may help troubleshoot this issue. Other than that, the KNX integration is working flawlessly, and I can both control KNX devices from HA and expose HA entities to the KNX bus, with the help of a knx: section I've manually populated in my configuration. Thank you!
