Describe the bug

I'm starting my Keycloak 23.0.5 instance in a docker container using a Postgres database also in docker.
I go into a realm/Realm Settings/Tokens and try to modify access token lifespan to, let's say, 1 hour. Click on save.

There is a java exception at the console:

```

```

After that, it is impossible to list realms in the corresponding drop box on top left.

The corresponding XHR request returns 400/unknown error.

I still have access to master realm.

But, if the modified realm is master itself, then keycloak stops working and doesn't even start again.

The database looks corrupted and the only way I found to solve this is to restore it from a previous snapshot. This is very annoying.

Version

23.0.5

Expected behavior

Modifying access token lifespan at realm settings level should not affect instance's health.

Actual behavior

Keycloak stops working when modifying access token lifespan at realms settings level.

How to Reproduce?

Go into a realm/Realm Settings/Tokens and try to modify access token lifespan to, let's say, 1 hour. Click on save.
Also do it for master realm.

Anything else?
