Error when opening two Matlab versions at the same time due to pathdef.m. How to fix it?

I use Matlab 2019b mainly because most of my project has been coded in that version, and therefore, I have set up a pathdef.m file with some functions that I've written. However, when I want to produce graphs, it is easier and nicer to use Matlab 2021b. Everytime that I open Matlab 2021b, while pathdef.m is in my home directory, it fails with multiple errors (see at the end). The only way of opening Matlab 2021 is for me to rename pathdef to something else, and then change it back when I want to use Matlab 2019b. This is not ideal for me, so I would appreciate if anyone could help me figure out how to be able to open both Matlabs without having to modify pathdef.m
Thank you!

In all the versions of MATLAB I have, pathdef.m is in
$MLROOT/toolbox/local/pathdef.m
I don't know why you have pathdef.m in the home directory.

Each version of MATLAB should have it's own pathdef and be independent. You can add paths to it with the Set Path button on the toolbar, but may not (at least in Windows) be able to modify it yourself. But you should not do that anyway. If you have custom paths you want to set up, do what I do : use addpath() in your startup.m file. I have my startup.m file in the Document/MATLAB folder. When I install a new MATLAB release, I just use the Set Path button to point to that folder so the startup.m file will get run. You only need to do this once, just after installation. Once that's done, all your versions of MATLAB will run the same startup.m file and thus will have the same folders added to the search path.

It is an institutional computer, so I have very limited access to any folder outside my home.
I had understood from your previous comment that it was enough to have one startup.m file, as both Matlab versions could use the same one. Is that assumption wrong?
When I used "edit(fullfile(userpath,'startup.m'))", it opened a file that was inside my home/matlab folder. I have added the paths this way:
%------------- ADD PATHS -----------------------------%
addpath /home/user/Scripts
addpath /home/user/matlab
addpath /meg/meg1/software/brainstorm3
And I am about to test it out.
