ACR 17.5 GPU memory leak / extremely memory hungry

Question

ACR 17.5 became very GPU memory hungry.

It takes only one Sony's RAW file to open via Bridge, make some basic adjustements, denoise, make a few masks (eg. select subject, select object, brush, create mask by duplicating inverted, etc) and ACR consumes whole 24 GB of RTX 3090 card (system (Win 11) with e-mail client, web browser and Bridge opened consume about 700-900 MB of GPU RAM).

Then I close ACR, close Bridge, reopen it, open the same file in ACR (including the masks prepared earlier) and do nothing, watching as VRAM ocupation curve in Task Manager's Performance tab climbs slowly till it reaches the max capacity and the 'Out of GPU ram' tab apears (as shown on the attached screenshot).

I'm working on Win11, i7 11700K, 32GB RAM, RTX 3090.

I post it as separate bug report as @Aleke told me to do.

Yeah same here. After a few edits I have to close Bridge completely because my VRAM is full and it's also using more than half of my system shared memory. On my PC, that's more than 50GB of used memory after editing about 30 photos!
