Photoshop 2025 26.0 crashes after opening the flash screen

[Fastidious]

I upgraded to Photoshop 2025 26.0. It crashes when opening the flash screen. I replaced 25.9. I tried uninstalling 26.0 and reinstalling 25.9; it no longer opens- same crash. I have uninstalled and tried Beta; it crashes. After uninstalling I have tried Adobe Cleaner and deleted all the previous setting files in Preferences and Application Support. I have a MacBook Pro 2022 with M1 Max and 64 GB memory. I just installed the upgrade to MacOS 15.1.1 and reinstalled 26.0. Same results. I have tried to download the error logs than ran under 15.1, attached.

I also have a MacStudio where 26.0 was installed and is working perfectly.

It seems that the ON1 plugins are the cause of the crashing.

When starting Photoshop 2025 hold down the Shift key to Skip Loading of optional and third party plug-ins

and see if Photoshop opens without crashing.

YES! That worked. I will have to let ON1 know. Thank you!

I got the answer from ON1 support. The problem is old ON1 plugins prior to 2025. I went into the CC location and deleted all the old plugins.
MacintoshHD>Library>Application Support>Adobe>Plug-Ins>CC

Thank you all for your advice.

That worked for me as well. The advice from Fastidious didn't accomplish anything, only holding the shift key while loading allowed it to open. I had just installed the latest On1 Photo Raw with plug-ins and will let them know.
