Updated to v26.2.2 yesterday after it crashing in previous version - now I'm getting error code only solution is to uninstall

I would recommend that you please roll back to the previous version once to test.

> Please open the Creative Cloud Desktop App first.

> Next to “Premiere Pro” Application's Name > there are 3 DOTS

> Click on 3 DOTS > Choose "Other Version"

> Select the desired last stable version, 26.0.2, from the list, then click INSTALL.

I wanted to share what finally fixed this for me in case anyone else is dealing with the same nightmare.

After updating Premiere Pro to 26.2.2, Premiere started crashing non-stop on launch. After Effects was also unstable. The first crash was related to GPUSniffer.exe, and after trying older Premiere versions, Premiere itself would still crash before I could even open a project.

My system:

• Windows 11

• CPU: AMD Ryzen 7 7800X3D 8-Core

• GPU: AMD Radeon RX 9070 XT

• RAM: 64 GB

• Storage: around 3 TB SSD free space

• AMD Adrenalin 26.5.1

• Also had integrated AMD Radeon graphics showing in Task Manager

What I tried:

• Installed older Premiere versions: 26.0.2 / 26.0.1 / 26.0

• Reset Premiere cache/plugin cache/preferences

• Repaired/reinstalled AMD Adrenalin driver

• Fully uninstalled Adobe apps

• Used Adobe Creative Cloud Cleaner Tool

• Deleted leftover Adobe caps database files

• Reinstalled Creative Cloud and Premiere clean

None of that fixed the GPUSniffer crash.

What finally worked:

I went to:

Windows Settings → System → Display → Graphics → Advanced graphics settings

And turned OFF:

Hardware-accelerated GPU scheduling

After restarting the PC, the older Premiere version opened again.

So in my case, the issue was not my project, not my keyboard shortcuts, not my presets, and not a normal Premiere cache issue. It seems related to Premiere/GPUSniffer + AMD GPU/driver + Hardware-accelerated GPU scheduling.

I spent roughly 3+ hours troubleshooting this, including a full Adobe cleanup and reinstall, and the actual fix was disabling Hardware-accelerated GPU scheduling in Windows.

Hopefully this helps someone else avoid wasting the same amount of time.

In that case you need to deinstall use cleanertool and reinstall.

Reboot between actions.

Use the Adobe Creative Cloud Cleaner Tool to solve installation problems

Make sure if you have an Nvidia card to update (manually/fresh install)  to the most current studio driver.

Trash preferences and medic cache.

Try and find an auto save or backup file that will open.
