Software Question: Has anyone else ever had Auto-Supports stop working?

I use the Photon Slicer software for my supports, and previously my workflow was use a low-density Auto Supports to rough out placement, then go through and manually add/ delete. Recently, when I click Auto-Supports, I get a split-second alert window, then nothing, and no supports are generated.

I've removed and reinstalled the software, thinking that might fix whatever's wrong, but the problem persists.

I can still manually place supports, and I've had no problems with the .photon file generating.

I think the SLA gods approve of the new shelf, but they still do not give full blessing.. Massive info download below, I've been trying to rule out as much as possible:

- I cleaned my plate & vat thoroughly, re-leveled it before I ran this print.
- I'm using Anycubic brand Black resin, which I shook for 5 minutes solid to make sure I had a good mix.
- Followed the Google Doc's recommended program for Anycubic Black - .025 Layer Height, 7.5 Normal Exposure, 3.5 Off Time, 90s Bottom Exposure, 3 Bottom Layers.
- My print room can get pretty cool, so I let my space heater run in there for a bit to warm the room up to mid 60F
- Used Meshmixer's Analysis > Orientation feature on each mini. MM's supports, were first autogenerated, then forced a few additional in parts I thought needed more help. Included a screenshot of my settings.

Worth noting -- the last 2 prints I've run, the bottom of the vat clung to the LCD and wouldn't slide out easy. Enough so that when the vacuum broke, there was a good 'pop' as the seal broke. During printing, I heard nothing out of the ordinary. There was no residue on the LCD when I cleaned (I gently ran a razor over the LCD to check, no snags or residue). Could the FEP need replacing? It's a bit cloudy, and does have a few marks & crease lines in the plastic, particularly with this Anycubic Black, since the supports are much, much harder to knock off with the scraper.

Frustrated by some failed prints (switched to anycubic black resin from the starter green), so instead of rage printing, I put together my shelving for a print/ cure station.

Taking advice from previous posted fails, I did run the files through validator. Super helpful in picking out islands, as many of the supports were a point or two off from the islands. Much farther along, but obviously still a fail.

The model is an Knight Artorias off of Thingiverse. I cancelled the print where you see the clean shear at the “face”

Mini 2 is the tmnt mini that was previously a fail, now 100% success.

Mini 3 was the cleric mini that kept printing with no head.. Got head this time (teehee), but his weapon stuck to the plate in a similar fashion.

Sucks because the cleric is a gift for my a player in gaming table tonight.. ?

Thinking it’s the scaling & positioning causing some adhesion on the thinner parts

Seems like the first run was beginner's luck.... Any suggestions/ fixes as to what's causing this? First pic, the mini's body printed fine, but his head didn't print (nor did the supports, and the second pic was printed on his back, the legs being completely flat..

Not bad for my first 7 prints!

First test run has begun -- run time 2 hrs. Did not drink the resin clearly labeled as extremely toxic.

It's about the little victories.
