Is lingotek translation compatible with WordPress 6.1 ?

Is lingotek translation compatible with WordPress 6.1.1 ?
I have unwanted behaviors on my current WordPress instance.
So I tried a full reinstall from scratch of WordPress and plugins and I can reproduce the problem.
Steps to reproduce :
1) Install WordPress 6.1.1
2) Install polylang lugin, configure with french and german
3) Install lingotek translation plugin. configure with new lingotek account. Set “etiquettes” (tags) to “manual” on “content type configuration”
4) Create a tag
5) Attempt to “Upload to Lingotek” => Error message :

Warning: Attempt to read property "post_type" on null in /path_to_my_files/wp-content/plugins/lingotek-translation/include/model.php on line 390 Warning: Attempt to read property "locale" on bool in /path_to_my_files/wp-content/plugins/lingotek-translation/include/model.php on line 201 Warning: Attempt to read property "locale" on bool in /path_to_my_files/wp-content/plugins/lingotek-translation/include/model.php on line 202 Warning: Attempt to read property "locale" on bool in /path_to_my_files/wp-content/plugins/lingotek-translation/include/model.php on line 203 Warning: Cannot modify header information - headers already sent by (output started at /path_to_my_files/wp-content/plugins/lingotek-translation/include/model.php:390) in /path_to_my_files/wp-includes/pluggable.php on line 1416 Warning: Cannot modify header information - headers already sent by (output started at /path_to_my_files/wp-content/plugins/lingotek-translation/include/model.php:390) in /path_to_my_files/wp-includes/pluggable.php on line 1419

Does anyone have the same problem?
I will write to Ligotek support in parallel.
