Short story...Is this heat damage?

less short story. .. I had many of my plants in a cheap greenhouse for the winter (if you call what we get in central Florida winter), but we had a day last month we the temp literally went from 40's one night to low 80's the next day or two. Greenhouse door was closed due to expected rain that didn't come, and quite a few of my plants were exposed to the heat and no air circulation. I lost a few plants completely and others were just damaged. I am just wanting to verify that this is heat damage and not just a coincidence in timing and something else.

The desert rose has the withered looking and now deflated root which was full the previous day. the skin on the root feels normal, not squishy or slimy, just deflated inside. It also has three dark spots that feel soft-ish. the rest of the plant seems fine. Subterranean roots do not appear to have any rot.

if this is just heat damage , can it recover? should i remove the damaged root? should i remove the dark spots from the caudex?

Thanks in advance.
