Comment 1 Méven Car 2019-07-19 10:05:00 UTC 
It could be related to the fact the BiglyBT_Installer.sh file, I guess you are mentioning, is a 12MB sh script embedding some binary data in file.
The stack trace seems to mention thumbnail creation crashing, so this may be the cause of the crash.

Also the script has some sudo calls in it that won't work from a double click.

In the meaning you can try to run the script from a console.
Comment 2 Patrick Silva 2019-09-09 19:00:28 UTC 
I forgot the last step...
4. After the step 3, a dialog shows up. Click on its "Execute" button

kio-extras 19.08.1
Operating System: Arch Linux 
KDE Plasma Version: 5.16.5
KDE Frameworks Version: 5.61.0
Qt Version: 5.13.1
Comment 3 Patrick Silva 2020-01-18 15:23:31 UTC 
still crashing...
1. download latest BiglyBT installer at
https://www.biglybt.com/download/
2. make it executable
3. double click on the installer and click on "Execute" button (a temporary folder appears in current location while files are extracted)
4. open such temp folder before the files extraction to be completed

plasma shows a crash notification
