Cannot burn 128GB BDXL disc

[SJason]

Hi everyone, I was trying to burn a Sony 128GB BDXL QL disc as UDF 2.01 yesterday. However, ImgBurn refused to burn it, saying "Too many UDF Extended File Entry AD's". The file I was trying to burn is a single zip file just over 128GBytes and a txt file <1KB.

I searched around in this forum, but only found this error occurring with 200GB+ images. I used to burn single 100GB files onto BDXL TL discs and this error never occurred. I tried UDF 2.60 but the error persists. Is there a hard limit on the image size? If there is, what is it exactly? Any help would be appreciated.

Here's the log (this was from yesterday when I tried to overburn, today I tried to reduce the image size to fit into the disc but to no avail):

Blimey, that’s a definite ‘check the code and see what’s going on’ type of question. Leave it with me and I’ll get back to as soon as I can.
