Lightroom Classic does not free up used memory

[MoBIoS]

Hello Adobe Team,

Issue:

On MacOS 13, Lightroom Classic (vers. 12.0.1) does not free up used memory when syncing cloud files, becoming unresponsiv and eventually forcing the macbook to shut down. 

SysSpecs:

• Macbook Pro 13" M2 with MacOS 13
• MacOS Ventura 13.0
• RAM: 24GB
• Internal HD: 1 TB
• Ext. HD: 2 TB

Software:

• Lightroom Classic vers. 12.0.1 (also vers.12.0)
• Lightroom CC Web (15.000 in cloud storage)

Prerequisites:

• granting all access to hd´s as advised in: https://community.adobe.com/t5/lightroom-classic-discussions/quick-tips-how-to-give-full-disk-access...

Re-produce:

• Objective: sync Lightroom CC Cloud Images into a new created catalog on a  Macbook Pro 13" M2.
• Catalog: saved onto internal MacOS HD 1 TB
• Images: syncing onto external 2TB HD
• After about 1-2hours the memory is used up by Lightroom Classic, provokes a MacOS out of memory warning and LR classic becoming unresponsiv.
• when trying to sync the 15k image overnight, the macbook will shut down, due to beeing out of memory.
• stopping the sync process in LR Classic,  leaving LR to idle, will not free up the used memory. 
• only a LR Classic restart frees up used memory

Expected behavior:

• Lightroom classic ver. 12.01 (and 12.0) will free up unused memory.

Please advice how to proceed with this issue.

I will be happy to provide further information, if needed.

So this didn´t go so well in terms of support. After nearly a month, I was hoping some feedback from Adobe support. Maybe an Adobe delegate can provide me with some informations as to where to post this bug. Please.
