Answer 1

Sorry it took me a while to get back to this. I see at least two major issues in the trace.log:

First, it appears your environment is misconfigured:

[main] [ 2021-02-03 15:09:37.030 GMT+03:00 ] [StepContext.:429] Error initializing Network Configuration: Environmental error detected: Oracle Home is set to "E:\oracle\client_19_3" in the environment is different from Oracle Net Configuration Assistant installed Oracle Home.

and second, it appears that you do not have enough physical memory on your host to run a database:
