I am using Python under Windows 10 on Dell for a log time.
All of my applications on Python were working fine.
Suddenly from the beginning of May, 
My apps do not update a "list" data after a new insert, 
even with small data volume.

As well as choosing old data from a list, 
a message appears stating that the identifier is out of range, 
and is working properly after restart.
Programs that do not use a list work fine.

After investigation, it appears memory issues.
How I solve the issue?
