The Bugbug bot thinks this bug should belong to the 'Firefox::Tabbed Browser' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Confirmed this is caused by KB5034129. After removal of KB5034129, these crashed tab issues are gone.

We'd like to explore if we can mitigate the crash or work around it, to make Firefox and KB5034129 no longer mutually exclusive. Can you maybe report a crash through the Firefox crash reporter and post the crash ID here?

How would I do that? Do you have a special build for me, or special instructions?

The crash doesn't appear in the crash reporter, nor about:crashes.
The details reported in "More details" above came from Windows event viewer.

Re-opening. Would be good to have some idea about the amount of affected users, and whether this patch is still being offered to users.
