You can try leveraging the terminal for this purpose. First navigate to the root of your project
cd <path to root of the project>
If you have the revision number of the version you wish to return to, use the "svn merge" command to revert to this revision version
% The "." reverts all the files to that specific revision number
svn merge -r HEAD:REVISION_NUMBER .
Commit the changes to the repository to finalize the revert
svn commit -m <Commit Message>
If you wish to use the MATLAB GUI to revert the changes, refer to the following documentation: https://www.mathworks.com/help/matlab/matlab_prog/work-with-files-under-svn-in-matlab.html#:~:text=and%20Revision.-,Commit%20or%20Revert%20Changes%20to%20Modified%20Files%20under%20SVN%20Source%20Control,-Before%20you%20commit
