libglib2.0-0t64 is a breaking change that supports 64 bit time types. If you can't get a chrome that works with it, you can force your libglib2.0-0 to a particular version by choosing one that is not t64. apt-cache policy libglib2.0-0. then apt install libglib2.0-0=<version>. then put a hold on that package to prevent upgrades apt-mark hold libglib2.0-0.
this is horrible to do, has global implications to your system, might break other packages, and you'll have to manually consider fixes that won't be automatically applied or suggested to you. but it IS an option to get it working immediately.
another option is to use a container-based chromium. snap, flatpak, whatever you prefer. I think you use ubuntu, so probably snap?
definitely best to get a chrome that works with updated libglib if feasible. there might be a non-stable that has it already, etc.
