Fatal exception and Disconnects WiFi Every 3 Hours or Less While Reading or Writing UART Data - serial-port

Question

I developed with ESPHOME and WEMOS D1 Mini to get my data from the RS232 port of my UPS device. Although currently working fine, my device loses wifi connection at intervals of 3 hours or less. I should also mention that my other ESP8266 devices connected to the same wifi network are connected for days and I do not have any connection problems.
In my research on the internet, there is information that it is caused by the general wifi settings and the problem will be fixed when the wifi settings are changed, but the issues are not closed as resolved and I have encountered many similar issues.
In the AP logs, information appears as “device disconnected or terminated”.
The codes I wrote below are available.
I look forward to your comments and suggestions for solutions to my problem.
