Hi @LasseLeon,
Thank you for reporting this issue, and our apologies for any frustration this is causing.
When you attempt to import an .mxf and After Effects closes, does the Crash Reporter dialog show up? If so, have you submitted a report with your email? These are very helpful to us when diagnosing crashing issues.
Additionally, would you be able to send us a sample .mxf file so we can check if the metadata is some how incompatible with After Effects? If the footage is sensitive, please
