Since you can reproduce the crash, please provide a valgrind log as described here: https://community.kde.org/Dolphin/FAQ/Crashes
> Since you can reproduce the crash, please provide a valgrind log as > described here: https://community.kde.org/Dolphin/FAQ/Crashes i prepared that, but since MEGA is starting Dolphin I can not manually start it with Valgrind. Is there a way i can "capture" the exact command line that MEGA is using to start dolphin? So i can reproduce from Konsole. Note: my running Dolphin windows are not affected. It seems to start a new instance which immediately crashes.
Thank you for reporting this crash in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the crash with a recent software version? If you can reproduce the issue, please change the status to "CONFIRMED" when replying. Thank you!

I just tried it with 22.08.1 and the current MEGA client and it did not crash!
