Mojang has made a weird thing that if you hold F3 and C to copy your position then it for some reason crashes after 10 seconds. This works on all version when this was added and i have proof of this: https://www.youtube.com/watch?v=sboaSs1ve8U
Also this is not a suggestion because i found this glitch in latest minecraft version, i did not tested it in some other version but it works on all minecraft versions, mostly 1.16+
