I exported a v1.10 fcpxmld for a 2 hour show and X2Pro5 created a 6 GB AAF without error. Embed media is enabled and Trim media is set to 2 second handles. The ProTools editor said that attempting to import the AAF caused PT to crash.
So I ran X2Pro4 with that same fcpxmld and it created a 16 GB AAF that opened properly in PT. Embed media is enabled and Trim is set to 2 second handles.
MacStudio M1 Ultra, 64 GB, macOS 13.1, FCP 10.6.3, X2Pro4 v4.5.16, X2Pro5 v5.0.25 (51)
Let me know how I can help you debug. I don’t see a way to attach an fcpxmld to posts here. The AAFs are large at 6 GB and 16 GB.
Thanks,

P.S. I submitted this issue here earlier this morning but now there’s no sign of it.
