Error (-50) in Photoshop when saving a .blp

Hey everyone,

I’m stuck with a frustrating issue in Photoshop:
"Could not save as 'MyFile.blp' because of a disk error (-50)."

I’ve tried everything I could find so far (and believe me, I’ve looked! 😅):

• Running Photoshop as an administrator.
• Checking folder permissions.
• Resetting Photoshop preferences.
• Disabling third-party plugins.
• Updating and fully reinstalling Photoshop.
• Disabling controlled folder access (thanks, Windows Defender... or not).
• Checking the disk.

But here I am, still facing the same error, and I’m running out of ideas. 🙃

If anyone has a clue, a hidden trick, or even a miracle solution, I’m all ears! Thanks in advance to anyone who takes the time to help. 🙏
