I personally couldn't waste anymore time troubleshooting this problem. Ensure you are using a Smartcard Reader that is compatible with the CCID (Chip/Smart Card Interface Devices) and ICCD (Integrated Circuit(s) Card Devices) driver.
Supported CCID readers/ICCD tokens: https://ccid.apdu.fr/ccid/supported.html Here are some Smart Card Readers that were intermittently working in Linux: [ray@ThinkPad ~]$ lsusb Bus 005 Device 021: ID 0bda:0165 Realtek Semiconductor Corp. Smart Card Reader Interface Bus 003 Device 003: ID 058f:9540 Alcor Micro Corp. AU9540 Smartcard Reader The Realtek Semiconductor Corp. Smart Card Reader Interface (0bda:0165) is actually a Stanley Global SGT111 Smart Card Reader. The Alcor Micro Corp. AU9540 Smartcard Reader (058f:9540) is a smart card reader that I added when I bought my Lenovo ThinkPad T14 (not knowing that it had compatibility issues with Linux). After running pcsc_scan, I could see the both of the above card readers fluctuate between: Card state: Card removed AND Card state: Card inserted. This would cause my VMware Horizon Client to randomly disconnect from Desktop Anywhere (very annoying). Here are the Smart Card Readers that I ended up buying on Amazon and eBay because they are fully supported by the CCID driver: SCM Microsystems Inc.

After a few seconds, it comes back and everything's happy. Then the cycle repeats again and again and again.
