May I ask more details about this? As we run a lot prints over 100C bed temperature, but first time see similar issue.
Is that the handle goes crispy after running long-time under high temperature or it cracked itself?

Is it the first time you run a printer over 100C? The handle went crispy when you touched it?

Would you like to give us more details? As it is really the first case we meet with such damage.
The handle wrapped first and then snap off itself?

Check photos. You can easily see glossy glaze on broken edges and also bends, folds. Honestly. It should be made from high-temperature silicone... What material did you use?

That's the reason why we choose this material and it is really the first time we meet such issue from the beginning of testing Pro2 series to now.
Please contact our technicians from help.raise3d.com. If it is really a special case caused by heat, we will cover the warranty for this.

I've had my Pro2 for almost 2 months. I've never set the bed temp above 90c and you can see my handle is starting to warp as well. I never pull the plate out so I'll probably not break the handle but I can see where this could (and will) be happening more often.

The warped section in your picture looks like the end of the thread of the fixing screw for the handle.
Please help check whether the warp is due to the screw or not.

Not screw. By heat and we know both why. The problem is material. Period. We have two factors here. Temperature - heat and isopropyl alcohol. Both works wrong with the used material. You should use a heat-resistant silicone.
