Cannot escape string

Hello,

I have a weird issue... I cannot create a correct escape string for Powershell for the following string:

,<Tx|Xo"{+8W

I tried several version, but it always returns an error (different). Once I fix one error another appears. See the screenshot below.

Do you please know who to correctly scrape the string to be able to correctly run the command? I also tried to use a variable, but the result is the same. Thank you.
