Sometimes latest versions of the software can cause issues when installed on older devices or devices running an older version of the operating system.

Software makers usually fix these issues but it can take them some time. What you can do in the meantime is to download and install an older version of Prusa Slicer 2.6.1.

What's new in this version:

Improved Arrange Tool:
- The Arrange feature has been significantly improved and it is now able to place objects inside concave areas formed by other objects

Currently there are three distinct levels of geometry handling, which can be selected using a drop-down in the Arrange dialog:
- Fast – essentially the old behavior considering only the convex hulls of each object
- Balanced – still reasonably fast profile considering the full shape complexity of objects which are not being arranged and the convex hull of the currently arranged object.
- Accurate – considers the full shape complexity of each object at all circumstances

- “Balanced” profile produces very similar results to “Accurate” in most cases but it is typically faster by multiple orders of magnitude
- As another improvement, arbitrary bed shapes are now supported

Cut Tool Improvements:
- New cutting mode is now available in the Cut tool. Dovetail mode automatically creates a tongue-and-groove connection that allows sliding one part into the other. The geometry of the connection is adjustable in the Cut tool dialog. Also, a new connector type was added (Snap).

Text Embossing Improvements:
- The Emboss tool introduced in 2.6.0 now allows much better projection on curved surfaces. The feature is accessible through a Per glyph orientation checkbox in the the Emboss dialog. When checked, the individual glyphs are (perpendicularly) projected along a curved line on the surface. The idea was inspired by the implementation in BambuStudio.
