It doesn't seem like it should be stressful, no, but prior to the crashing I noticed an uptick in the fan when I opened crates. There may be some weird or poorly optimized code involved from when crates had to sync with the server. Obviously I can't say with absolute certainty, but a hardware swap on the same software version fixed it and that's indicative of something.
I just bought the game last week. I have a Scorpio Edition Xbox One X and the loot box crashes are happening for me too. Every time. When it reboots I get a warning saying that the system shut down to protect itself from overheating.
