SQL Developer fails to start: Enabling a Security Manager is not supported

Hi,
I cannot start SqlDeveloper 26.02 on Fedora 44, it fails with error:
A command line option has attempted to allow or enable the Security Manager. Enabling a Security Manager is not supported.

for a life of me I cannot find how to make it run.
I've already removed all my old SQLDeveloper configs (renamed the ~/.sqldeveloper dir) and explicitly disabled Security Manager in internal SQLDeveloper config files:
/opt/sqldeveloper/ide/bin/ide.conf:AddVMOption -Djava.security.manager=NONE

yet still it crashes.
I don't think I have some JDK config leftover files and there's nothing in my envs.

Any ideas? I'm assuming no Java app released in 2026 should use it.
