Hi,
I am afraid that not a lot of options exist...
TC 10 is quite outdated version and is not supported for a long time already. At the same time there are a lot of changes in the security and access to internals between Windows 2012 and 2019. So I think that there are practically no chances that something will be changed for TC 10 even if some problem for Windows 2019 exists.
Any reason not to upgrade TC? (Except that the maintenence support has probably ended and full license renewal may be required. Though even in this case you may contact your Sales representative and talk about possible options.)
