[ovirt-users] Can't use ovirt web interface (500 error)

Hi, After updating to the latest version of ovirt (standalone installed with engine-setup) I am no longer able to use the web ui. After I log in, in fact, I get a modal error entitled "operation canceled" and with content "a request to the server failed, error 500" Looking at the requests it actually receives an error 500 when it goes to make a request to "/ovirt-engine/webadmin/GenericApiGWTService" which replies "The call failed on the server; see server log for details" These are the last lines of the engine.log: https://pastebin.com/uFgZASuW Is anyone experiencing the same problem or know how to fix it?
