Not costly in anything but time, but I tried to crossgrade an i386 server to x86_64. Eventually it got broken enough that I restored from a backup and just rebuilt a new server from scratch in a VM to replace it.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I installed some library from sources on my working laptop, and it stopped booting lol. Had to change my laptop for the newer Thinkpad, because you cannot insert into working devices any flash drives to boot from and fix the system. It hasn't cost me anything, but was pretty funny
That is a process fail, not a Linux fail. It wouldn't matter if it was Linux or absolutely anything else.
