I don’t know if I’m the only one who has this issue but right clicking on a folder or file or clicking the context menu key on my keyboard can sometimes/often freeze my Dolphin on CachyOS. This seems random and whenever it happens, it will always happen on that same file or in the same folder and the only workaround as far as I know is to reboot my laptop.
Service menu/context menu actions are a double edge sword.
This happened to me yesterday, dolphin froze for about 30 seconds (guess) each time I right clicked into a folder. Stopped happening after closing and reopening dolphin, though.
