Custom Sequences Not Opening or Deleting After Update to v25.3.84

After updating to Premiere Pro 2025 version 25.3.84, I can no longer open or delete sequences that I created and saved with a custom name (custom sequences).
Only the default system sequences still work as expected.
But when I create a new sequence, give it a name, and save it — I cannot open it afterward, and I also can't delete it.
This issue started right after the latest update.

My system configuration:
OS: Windows 11 Pro
CPU: Intel Core i9-9900K
RAM: 32 GB
GPU: MSI RTX 2060 Super
Project drive: Lexar NM620 2TB NVMe SSD
Premiere Pro version: 25.3.84

Please let me know if this is a known bug or if there’s any workaround. Thank you.
