Image Export failed exception when converting ICO to pdf

Hello team, we are getting a exception “Image Export failed” when trying to convert ICO to PDF
here is the ICO file and sample code of conversion

currently we are using GroupDocs.Conversion 23.1.0 and .NET framework 4.6.1

can you help us here . I see there is an enhancement related ICO in 23.1.0 CONVERSIONNET‑5746. is this something causing this issue?

@MeghanaVaitla

We cannot reproduce this issue using API version 23.2 or newer. Could you please try again with 23.2.

as GroupDocs.Conversion 23.2 supports with .net framework 4.6.2. we can can’t update as we are still using .Net Framework 4.6.1.
are tehre any other solutions or workaround for this?

@atir.tahir I’m unable to access Free Support Policies How much time will it take for free support when compared to paid support?

and Just to confirm the fix will be available for 23.1.0 right? As latest version don’t have an issue and we need a fix for 23.1.0 as we are using .NET framework 4.6.1

@MeghanaVaitla

We will investigate this scenario and notify you in case of any update.

@MeghanaVaitla

We could reproduce this issue in Conversion 23.1. As you cannot update to Conversion 23.2 and later due to .NET Framework version limitation, then we would suggest you to use Conversion 22.12.
