You may not have to reinstall. First thing is to ascertain what you did to your bash and if it was system wide or just for your user ID.

Create a new user ID and see if it works normally. If so there is no damage done to 18.04 just for your old user ID.

Ubuntu keeps a β€œskeleton” of most configurations that get copied to when a new user ID is created. For .bashrc it is in /etc/skel/.bashrc:

$ llocate .bashrc
ACCESS      OWNER  GROUP  SIZE  MODIFIED      NAME (updatdb last ran: 2018-10-06 10:30:06)
-rw-r--r--  root   root   2188  Aug 31  2015  /etc/bash.bashrc
-rw-r--r--  root   root   3771  Aug 31  2015  /etc/skel/.bashrc
-rw-r--r--  rick   rick   7522  Sep 30 10:10  /home/rick/.bashrc
-rw-r--r--  rick   rick   7492  Sep 30 10:09  /home/rick/.bashrc~

If you modified .bashrc and damaged it there may be a backup called .bashrc~ which you can copy over top.
