I recently hat troubles with a stable debian and trying to install the Citrix Workspace.

Citrix need libwebkit2gtk-4.0.so.37 which is no more available in Debian 13.
My solution was to install the old packages manually. As could not notice any side-effects as of now.

This are the packages that you need to install:

  • libavif15_0.11.1-1+deb12u1_amd64.deb
  • libdav1d6_1.0.0-2+deb12u1_amd64.deb
  • libicu72_72.1-5+b1_amd64.deb
  • libjavascriptcoregtk-4.0-18_2.42.5-1~deb12u1_amd64.deb
  • librav1e0_0.5.1-6_amd64.deb
  • libsvtav1enc1_1.4.1+dfsg-1_amd64.deb
  • libwebkit2gtk-4.0-37_2.42.5-1~deb12u1_amd64.deb

You have to give it a try, I did not write down the sequence...
