What drive are you exporting to? The Samsung T5 external? How is it formatted?

I am guessing that it is NTFS, given that you are using the paragon software (see below).

That is not a good idea.

Does exporting to the internal drive also crash?

If the T5 is indeed NTFS formatted, you should copy off the contents of the T5 to another drive, and reformat as APFS.

/Library/Extensions

[Loaded] ufsd_NTFS.kext - com.paragon-software.filesystems.ntfs (15.4.19 - SDK 10.10)

[Not Loaded] SamsungPortableSSDDriver.kext - com.samsung.portablessd.driver (1.5.02 - SDK 10.7)

You should also definitely uninstall this old Samsung driver. It is not needed and may well be interfering with the operation of the drive.

These agents are installed by chrome and are the bane of FCP and other professional applications.

You need to uninstall those, and then drag FCP to the trash, and download a new copy from the App Store.

Whenever a crash occurs, delete the application's preferences.

Crash reports are really only decipherable by engineering.
