Adobe Acrobat 26.1 repeatedly crashes during scanning (Scan.api) on Windows 11

My job is to scan tens of thousands of documents. With this workload, any slowdown on productivity represents a risk on the long term.

I'm experiencing persistent crashes in Adobe Acrobat while scanning. The issue has been ongoing for several months and continues after updates and a reinstall.

Environment:

• Adobe Acrobat 26.1.21662 (also occurred on previous 26.x versions)
• Windows 11 Pro
• Intel Core i7-14700
• 16 GB RAM
• Intel UHD Graphics 770
• Ricoh Fujitsu fi-8170 (Scanner)

Symptoms:

• Acrobat crashes almost exclusively during scanning or immediately after initiating a scan.
• Most crashes occur while scanning multi-page documents, although they have also happened after short scans and even shortly after opening Acrobat.
• The scanner itself does not consistently report an error; Acrobat is the application that crashes.

I've collected multiple crash reports, and although the exception codes vary (including 0xC0000409 and more recently 0xC0150014), they consistently reference Acrobat's scanning components, particularly Scan.api and CreateGlobalScanHelperInstance.

Things I've already tried:

• Repairing/reinstalling Acrobat.
• Updating Acrobat to the latest version.
• Testing different scan compression settings (JPEG2000 and JPEG). The crashes occur regardless of the image format.

Since the crashes consistently point to Acrobat's scanning module, I'm wondering if this is a known issue with the scanning plugin, TWAIN/WIA drivers, or compatibility with recent Windows 11 builds.

Has anyone experienced similar crashes involving Scan.api or found a workaround? I'd appreciate any suggestions.
