I fixed this bug by removing the libtcmalloc_minimal.so.4 library in the bin folder in the tf2 folder and making a symbolic link to the libtcmalloc_minimal.so.4 library from the system. But it is worth installing packages, by command sudo dnf install gperftools gperftools-devel gperftools-libs.i686

Note: create a symlink from /lib/libtcmalloc_minimal.so.4
Note 2: cd to .local/share/Steam/steamapps/common/Team Fortress 2/bin/ then ln -s /lib/libtcmalloc_minimal.so.4

Audio might not play so type into terminal on fedora: sudo ausearch -c 'hl2_linux' --raw | audit2allow -M my-hl2linux and sudo semodule -i my-hl2linux.pp


OR

sudo dnf copr enable kylegospo/hl2linux-selinux
sudo dnf install hl2linux-selinux
sudo setsebool -P selinuxuser_execheap 1

LLVM is having issues recently,
sudo dnf install gperftools-libs.x86_64 then set your launch commands to LD_PRELOAD=/usr/lib/libtmalloc_and_profiler.so.4 %command%

This will fix LLVM issues.
