DspMixFx freezes when trying to change reverb type, amp or other settings

I have a Steinberg UR44 on a PC with Windows 10 x64. Whenever i try to change the Channel Strip for a Clean amp, or any other amp, the software interface freezes. The problem also occurs when a i try to change the reverb type in the drop-down menu. It also happens if i try to change the input level on the 5/6 channel (that drop-down menu that has the -10dbV/+4dbu options) or the HPF. Sometimes, randomly after using the pc for a couple of hours, i can change those options. But it’s very rare.
Any suggestions?
