ADDITIONAL INFORMATION
Specific VERSION with this problem is 5.20.0-0xneon+20.04+focal+build10 downgrading to 5.19.5-0xneon+20.04+focal+build9 is a workaround to maintain activities working with no noticeable drawback.

Also, https://bugs.kde.org/show_bug.cgi?id=426963 Talks about a crash on version 5.20, but I don't know if its related or not. Their trace back is not a segmentation fault, so opted for opening this ticket.
