Blender Version

Short description of error
Blender crashes when I try to change the cycles render output file path. The output path will not change and it will not accept an output file name change either. Using the Preferences to directly set up an output file path also crashes. Its seems that any way I try to change the output file path it will fail and crash.

  • Clearing the cache did not help; I do not believe that too little memory is the problem here, but really don't know either way what has gone wrong.
  • This is a "new" crash problem that did not happen in any previous version of Blender, nor in any of my renderings with 2.82 up until just recently. Something changed at the last software update that I am not able to identify.

Exact steps for others to reproduce the error

Based on the stack trace and the provided hardware information, the issue seems to be caused by unsupported hardware that doesn't fulfill the minimum requirements for running Blender 2.8x. AMD Caicos is the codename for the Radeon HD 6450 which has the TeraScale 2 microarchitecture. Blender 2.8x requires GCN first generation or later.

You may be able to run Blender with updated graphics driver, but we do not provide support for hardware below the minimum requirements. If an updated graphics driver doesn't solve the problem, you will likely have to use an older version of Blender with lower requirements.
