/lib/x86_64-linux-gnu/libstdc++.so.6: version `CXXABI_1.3.15' not found (required by ./SVPManager)

When attempting to launch SVP's internal MPV from the command line, I get:

./mpv/mpv: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.38' not found (required by ./mpv/mpv)
./mpv/mpv: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.39' not found (required by ./mpv/mpv)

Note, when installing SVP, I just went with the options to have the SVP installer download and install all needed components.

So far, I've focused on the `CXXABI_1.3.15' not found error. libstdc++6 was checked to be up-to-date.
It appears an up-to-date version of libstdc++6 does not contain CXXABI_1.3.15, as evidenced by executing:

strings /lib/x86_64-linux-gnu/libstdc++.so.6 | grep CXXABI

resulting in:

CXXABI_1.3
CXXABI_1.3.1
CXXABI_1.3.2
CXXABI_1.3.3
CXXABI_1.3.4
CXXABI_1.3.5
CXXABI_1.3.6
CXXABI_1.3.7
CXXABI_1.3.8
CXXABI_1.3.9
CXXABI_1.3.10
CXXABI_1.3.11
CXXABI_1.3.12
CXXABI_1.3.13
CXXABI_TM_1
CXXABI_FLOAT128

Note, running the same search on libstdc++-11 and 12 produces the same result as well.

Does this mean the dependency is un-resolvable under Debian 12 and SVP can't be used under Debian 12?
I saw another post here that mentioned this same error, but it was not entirely clear how the poster got past it.

They said they "updated the operating system", but did not specify if that mean't updated to Debian 13 or what.
(Updating to Debian 13 isn't really an option for now.)
Any insights or help appreciated. Thanks.
