We do monitor User Voice; we share your disappointment that we don’t have a reproducible case, for this issue.
If you can reliably reproduce the ‘low level exception’ problem, on your system, please contact Support and provide them with any files and source media required for that repro case, as well as (important!) step-by-step instructions on how you can reproduce the issue.
We’re eager to pursue the issue further.

Big problem with Export: It´s written: low level exception - can´t export with H.264. System stopps.
I switched back to version 2019 - now it works. That can´t be the solution!??
