Substance 3D Painter 12.1.3 random crashes on Windows – is this a known issue?

Hello,

I purchased Substance 3D Painter 2026 on Steam on August 27, 2026, and I am using version 12.1.3 on Windows.

During actual production work, I have experienced frequent random crashes, errors, and unstable behavior. I tried restarting the application, changing settings, and repeating work after crashes, but the instability has made it difficult to use reliably for professional production.

I found Adobe’s official announcement published on August 28 regarding random crashes in Substance 3D Painter 12.1.3 on Windows:
https://community.adobe.com/announcements-57/12-1-3-random-crashes-1639216

Could you please confirm whether the random crashes I am experiencing may be related to this known issue in version 12.1.3?

I purchased the software specifically for professional production work, but because of the frequent instability, I am currently unable to use it reliably.

I submitted a refund request to Steam, but it was declined because my usage time exceeded the standard two-hour refund limit. After that, I checked the technical support options for the product on Steam, and Steam’s product support page links to Adobe’s support/community for product-specific technical issues.

For this reason, I would appreciate it if you could confirm whether random crashes on Windows are currently a known issue in version 12.1.3, and whether rolling back to a previous version is currently the recommended workaround.

Thank you very much for your help.
