Application Crash StackHash_2264

[new90]

Application crashes without any messages at all local network hosts when connecting to any database (even unexisting).
When cancel connection - application starts normally, but closes unexpectedly when try to connect to any DB.
The same happens in PL/SQL Developer 12.2 and 14.0 version of Application with Oracle client version 12.2, 19 and 21. With full client and instant client only - result is the same.
The problem has started at ~15.01.2022 and still is not resolved.

Is there any way to print detailed debug information during connect?

Problem siganure from Windows 10 application log:
P1: plsqldev.exe
P2: 14.0.6.1988
P3: 60478f00
P4: StackHash_2264

To obtain some more diagnostic information, can you modify the PL/SQL Developer shortcut and add the DebugSQL parameter? For example:

"C:\Program Files\PLSQL Developer 14\plsqldev.exe" DebugSQL

Reproduce the problem and send me the debug.txt file that is generated in the %APPDATA%\PLSQL Developer 14 directory (e.g. C:\Users\\AppData\Roaming\PLSQL Developer 14).
