P: New 23.3 update bug exposure with mask in 32 bit

So. I update today. I have simple action which I have been using for many years to supress highlights -

• in 32-bit image create ajustment layer "exposure"
• Apply image to mask of this layer
• Apply exposure to the mask (gamma correction) to separate dark and light in the mask
• Feather mask 
• modify in exposure layer option "exposure" to -0.3

And now in 23.3 all highlights turn to BLACK SPOTS. 

Again - i have simple exposure layer with mask, in this layer i change only "exposure" to -0.3 and this turn white color to the black! what [removed]? It breaks all logic.

А back to 23.2 and here all works fine.
