Hi Gunther,
I tried the new beta 2 and unfortunately the "Wrong LRTExport Version" error is still present.
I closed Lightroom before upgrading and even restarted my computer (Apple M2 Max MacBook Pro).
In Lightroom the export version shows Lightroom 13.4 and LRTexport 7.1.0 build 968.
I tried a few different options with small sequences, all with the same result.
It's not a major issue since the workaround is simple.
Regards,
Eric de Jong

Sorry guys, if this is still an issue. I'm nearly off the grid for a couple of days so that I cannot really test. I tried to do a quick fix and hoped this would work. Will check and try to fix asap.

Should now finally be fixed in beta 3. Thanks for reporting!

Thanks! It works fine now.

Glad to hear that!
It's always more callenging to do such fixes while in a camper van in Danmark with really weak internet connection... ;-)
