Exporting the photos from Lightgroom Consume very huge time.

I’m trying to export a batch of 500 photos from Lightroom, but the process is extremely slow. After about 10 minutes, only four photos have been exported. I’m doing this on a Dell Inspiron 15 laptop with a Core i7 8th‑gen processor and 12GB RAM, so the performance slowdown is surprising. At this rate, it’s hard to estimate how long the full export will take while I’m still working on edits.
