Error when using DBCA to create database Oracle XE 18c
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 &quot;E:\oracle\client_19_3&quot; 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:
