致命错误：未捕获的错误：在应用程序/代码/DeviceDetector/Yaml/Spyc.php中找不到类“ Spyc”

Question

I am facing the issue with order placing on Magento ver. 2.2.2 . After complete the payment when I will redirect to website https://domainname/paypal/express/placeOrder/ page and error display on that page.

Please check the error below, 

Fatal error: Uncaught Error: Class 'Spyc' not found in /public_html/app/code/DeviceDetector/Yaml/Spyc.php:17 Stack trace: #0 /public_html/app/code/DeviceDetector/Parser/ParserAbstract.php(155): DeviceDetector\\Yaml\\Spyc->parseFile('/p...') #1 /public_html/app/code/DeviceDetector/Parser/ParserAbstract.php(243): DeviceDetector\\Parser\\ParserAbstract->getRegexes() #2 /public_html/app/code/DeviceDetector/Parser/Bot.php(53): DeviceDetector\\Parser\\ParserAbstract->preMatchOverall() #3 /public_html/app/code/DeviceDetector/DeviceDetector.php(623): DeviceDetector\\Parser\\Bot->parse() #4 /public_html/app/code/DeviceDetector/DeviceDetector.php(587): DeviceDetector\\DeviceDetector->parseBot() #5 /public_html/app/code/MageWorx/OrdersBase/Observer/OrderPlaced.php(107): DeviceDetector\\DeviceDetector->parse() #6 /public_html/vendor/magento/framework/Event/Invoker/InvokerDefault.php(72): MageWorx\\OrdersBase\\Observer\\OrderPlaced- in /public_html/app/code/DeviceDetector/Yaml/Spyc.php on line 17

The error is seems related to the DeviceDetector plugin but I don't know why this issue happen & I have check the particular lines mentioned in error but no solution found.

Please let me know how to resolve this issue. Thanks in Advance!

Can you add more details here, after what action this error start appear? If you inject this class somewhere in constructor then I suggest you to run rm -rf generated/* because M2 dont update generated folder automatically if you change class that already generated in generation. If its not work please share some context.
