Audio out of sync after exporting

[roses76153893]

First time a tried Premier Rush. I created a few MP4 clips (Sony A7III), imported and edited in Adobe Premier Rush.

3 Minute Video, everything looks great within Premier Rush. Clicked on "Share - Export" and once the Video is exported the Audio sync is off starting after about 1 minute in.

Here is what I tried so far:

- Disabled AV

- Closed and resopened Rush

- Make sure all updates for Rush are installed

- Export in 4K, 1080p Full HD, 24, 23.976, 60 Frame Rate, Custom, YouTube but nothing resolves this issue.

My Workstation Specs:

Processor Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz 4.00 GHz
Installed RAM 32.0 GB
System type 64-bit operating system, x64-based processor
Samsung SSD 970 EVO Plus 1TB

NVIDIA GeForce GTX 970

Any help is greatly appriciated.
