Iso - remaster script trying to start chroot run commands then exit but host system gets messed up

The script works and creates a modified iso fine until I added the chrootbeg and chrootend functions and executed them. I'm sorry if I did something wrong this is my first post. I uploaded entire bash script for reference or in case you want to run it to debug it is called isoremast.txt.

Please let me know if you need more information and I'll be happy to provide it. Thank you.

Summary of script

USAGE: isoremast (no options) - Will DL iso and uncompress image
isoramst m - Will modify the iso files by adding, deleting, etc
possibly by chrooting into the system
isoremast c - Will recreate the iso file with your modifications

Script was written to be run 'isoremast m' mult times in a row
and change the script to easily add or delete files without having
to recreate the iso each time - useful for rapid testing
Also several other proj do something similar but use a myraid of scripts
and programs to do so. Want all functionality need in 1 script this
is my goal along with simplicity so my 8 year old can run it
without having to type a myriad of commands into the terminal.

Setup - Running golang webserver on Win 7 host running Debian 10 as a VM guest running the script

NAME
Test::Script - Basic cross-platform tests for scripts DESCRIPTION
The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or bin as is also commonly used) paths of your Perl distribution. Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible. That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is considered unacceptable. In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking that your module won't on some platform because of the dependency. Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform safety. FUNCTIONS
script_compiles script_compiles( 'script/foo.pl', 'Main script compiles' ); The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. script_runs script_runs( 'script/foo.pl', 'Main script runs' ); The "script_runs" test executes the script with "perl script.pl" and checks that it returns success. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. SUPPORT
