Same here. Since the end of 2024.
It is a wider issue than just PowerPoint. Basically, any formatted text copied from Word to the clipboard seems to be corrupted (text/html is a blank string) and that causes the error. On the other hand, the formatted text can be pasted as PLAIN TEXT to all applications, including PowerPoint, Excel, Gmail in Firefox. By that way, however, we loose formatting like hyperlinks, styles, tables, etc.
Neither resetting (deleting) normal.dotm nor repairing/reinstalling M365 does not help. However, when I start WORD in SAFE MODE, the copy function works perfectly, with full formatting, no error message in PowerPoint. Note, I have no more addons (COM or startup) in Word, so this potential cause can be excluded.
