I'm running QGIS on Linux Mint 19.3 and I just upgraded to the latest version following the instructions found at https://freegistutorial.com/how-to-install-qgis-on-linux-mint-19/
Opened up fine the first time, now crashes upon launch. When launching from the terminal, I initially got this message:
QGIS died on signal 11Could not attach to process.
If your uid matches the uid of the target process,
check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user.
For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted.

Following the instructions found at https://qgis.org/en/site/getinvolved/development/bugreporting.html#bugs-features-and-issues ...I attempted to make a backtrace. Tried launching from the terminal again, and now I get this return:

I'm guessing this is the backtrace. I'm a newbie to QGIS and am not a programmer, so could someone to tell me what this means and what I might need to do please. Before anyone asks, yes, I already tried reinstalling.
