I have serious lags and bugs in Premiere Pro 26.3

Question

Since I got Premiere Pro v26.3, I started having problems after some minutes of editing, everytime I use the menu above, either to export, render or save. It stays blocked, says, “not responding” and sometimes starts a minute later. But, if I try to do the same while using shortcuts, seems to be ok.

Besides that, when working with heavy timelines, with several effects, it starts to work slow and make some bugs.

I didn´t have this issue with previous versions. My computer is very powerful, so I don´t get the problem. I even reinstalled Premiere, but didn´t solve the issue.

Could you please tell me what to do? Thanks!

Since the issue carried over after a reinstall, a few things worth checking, as a reinstall does not touch these:

1. Clear your media cache. Here is a walkthrough for how to do this the easy way. To do it manually, navigate to the file paths below.

Windows: <user name>\AppData\Roaming\Adobe\Common
Mac: /<user name>/Library/Application Support/Adobe/Common

Note: To reveal the Library folder on a Mac, open Finder, then open the Go menu from the toolbar at the top of the screen. Press Option to reveal the Library folder in the dropdown menu. Open the Library folder and continue along the file path above.

In the Common folder, delete two folders: Media Cache and Media Cache Files. Then launch Premiere Pro 26.3 with a clean cache.

Note: Opening older projects after clearing the cache may take some time while Premiere Pro rebuilds the necessary cache files.

2. Make sure you are on the correct GPU driver.

On Windows, use this walkthrough to identify your GPU and download the latest driver from the manufacturer. If you already know which GPU you have, use the links below to go directly to the manufacturer's site.
- NVIDIA drivers. Adobe highly recommends Studio drivers, not Game Ready drivers.
- AMD drivers
- Intel drivers
On a Mac, select the Apple logo at the top left of the screen, then select About This Mac. Select Software Update from the popup that appears. If an update is available, install it.

3. Update any third-party plugins from their manufacturer websites. Since the slowdowns show up on heavy timelines with several effects, an outdated plugin is a possible suspect.
