Server Error whenever I'm upload to my personal gallery

I’ve been having the same issue for months. What works for me is not pressing ‘okay’ on the dialogue box when the warning comes up and just waiting about 45 seconds. The item then saves to the gallery despite the warning. My cue to know it worked is when the window to save the item disappears from behind the dialogue box displaying the warning. And then I press ‘okay’.

I learned this accidentally through sheer frustration as I stared at my screen in irritation when trying to save a build for the 100th time after repairing and restarting my game for the 2nd time that day and still getting that stupid warning. Especially since the game is still crashing and save files are still corrupting so saving everything to my gallery is my only legit backup. Anyway, hope this helps someone.
