Hi,
Unity 2020 is only giving us problems on critical projects, we currently stick to 2019 TLS.
It's been like that since unity 4 basically, it's a lot safer to stick to the previous year version to be on the safe side and experiment now and then on what's new with the latest unity version, but not count on them for critical work. it back fires way too often...
but try it, on a copy of your project, if it works, then why not.
Bye,
Jean
