Since updating to current version of Bridge 13.0.3 (unsure of version I updated from) about 10 days ago, it is making my MacBook Pro nearly unusable without being plugged in because of massive CPU usage (2019 MBP with 64 GB RAM, on Ventura 13.4.1). I tried purging my cache and resetting preferences to defaults per the recommendations on this troubleshooting page (https://helpx.adobe.com/bridge/kb/troubleshoot-errors-freezes-bridge.html) with zero improvement--if anything, problem got worse. And resizing the previews in a folder with about 500 images (approx 1800 images, 1300 hidden) does nothing. It just reopened and demanded 200% of CPU time, now 1,019% of CPU time while in the background with me having done nothing but open it and hide it. My battery health is good and I can run this machine for hours unplugged while using web browser, video, citrix VDI sessions for work--with rarely a peep from the cooling fans unless it it's very hot in the house.
I also tried updating to Bridge beta version as suggested in this thread (https://community.adobe.com/t5/bridge-discussions/averaging-700-800-cpu-usage-on-adobe-bridge-2023) and that did not help--again, opening bridge, essentials view, tiny previews, folder with 500 images, and back to 1000% + CPU usage and fans coming on within a minute or two of starting up, without scrolling or selecting or doing anything.
What other options do I have to resolve this mess?
Worked with online support, and had to delete current Bridge and return to Bridge 2022 to resolve the issue.
Things tried during that troubleshooting session that did not work included
deleting with the Adobe Creative Cloud Cleaner Tool, then reinstalling Bridge 2023
shrinking cache size as low as 5GB
I think there were another one or two steps, but those are the ones I remember two days later, as I'm posting this
