Hello Team. I'm trying to run ExpertSDR3 on my MacBook Pro 11,1 i7-2,8GHz equipped with latest BigSur MacOS 11.7.10
No luck, never starts ... just crash.
Looking into log (see attached), I see multiple issues with error "is not a Qt plugin"
I also check backtrace.dump into EspertSDR3 dubfolder but it is a empty file
Any clue?

I did a quick verification ...

macOS BigSur 11.7.10 with ESDR3 v1.0.3Beta = perfectly works
macOS BigSur 11.7.10 with ESDR3 v1.0.4Beta = not working

Likely linked with openssl brew upgrade.

Note that when using brew, openssl is currently an alias of openssl@3, when ESDR3 should be referring to Этот адрес электронной почты защищен от спам-ботов.

If I recall correctly 1.0.3 Qt 6.2-6.3 was used, when 1.0.4 was build with 6.4 and above - there were chnages in ssl support fo *nux OSes

Hence, you may try two options:
1. Upgrade to Monterey (minimum), it is fixed there
2. If HW does not support macOS upgrade, then reinstall openssl to @1.1 in Big Sur
