Tracerviewer 3.4.1 - Error "UTF-8 has occurred while loading" when opening trace file.

[dvmierlo]

When using Tracerviewer version 3.4.0 and 3.4.1, I see an error "UTF-8 has occurred while loading". Tracerviewer version 3.3 can open the same trace file without any issues.

I have attached the generated Tracerviewer logs of version 3.3 and 3.4.1 when opening the tracefile.

I also got the same issue, and those steps in the README didn't help

The issue also occurs on 3.4.0, but not on 3.3.0
