If you have not already done so, get in touch with support as the moderator has suggested.
Since purchasing a framework 13 core ultra 125H in May 2025, I have run Ubuntu 24.04 lts (currently with kernel 6.17.0-14 and X11) and have had 1 freeze which I attribute to the nvme (which has not reoccurred since updating the nvme firmware).
At least one other forum member with an intel 125H had issues with the igpu that seem to have been resolved with a motherboard replacement.
