ObjApi does not function in v12.0.65 64-bit

We updated the version when we started the application and it listed this (with the flood version of ObjApi):

[2020-05-18 12:29:28.814]I Connection to ‘ShM2 (D2000 Kernel V12.02.065.s348)’ failed. Reason: Incompatible protocol version. Server protocol version is 348, client protocol version is 300.

After deploying the new version, it will not write anything to the API log, it just crashes. The last one in our logs is “Connecting to ObjApi”, that crash occurs when calling ConnectKernel.
Event Viewer crash:

If the objapi.dll library is run from another directory than the bin/bin64 directory of the D2000 installation, it is necessary to copy the libtzdate.dll library (located in the bin/bin64 directory) and the tzdata directory (located in D2000_EXE) there. The tzdata directory can be in the same directory as the libtzdate.dll library or higher in the directory structure.
