replace chr(0) by '\x00' in Spyder -> error

[klausthenikolaus]

Description

What steps will reproduce the problem?

• have data with a zero byte at the end of a string
• want to remove this zero byte for further string handling
• insert both methods into the code:
  a.replace(chr(0),'')
  a.replace('\x00','')
• try to exchange the chr(0) by '\x00' in the editor by CTRL-F ...(because 2nd statement is a bit faster)
• full code disappears, can be recovered by CTRL-Z

Hi @klausthenikolaus thank you for the report! Checking seems like this could be a duplicate of #21007 Could it be possible for you to update to a more recent Spyder version (>=5.5.0) and try again? Let us know if updating helps!
